Understanding Roaming on an Android Phone - Android Q&A, Help & Troubleshooting

There's a debate going on on a cruise forum I'm part of and a lot of bad info is getting thrown in. I thought I'd best ask the experts here and give them a definitive answer.
As you may or may not know cruise ships have their own mobile cell to allow mobile comms (I assume using satellite tech but that's not important!). People are claiming that once you are out of reach of a terrestrial signal with roaming turned on (as you need it to be to use free data/comms in the EU) your phone automatically jumps onto the ships cell and can then incur no end of costs for use of data and/or calls and texts. I have always thought that my android mobile won't jump onto a chargeable network (i.e. one that my provider does not have a free deal with) without asking me but I'm no where near 100% sure of that.
Does anyone have the patience to explain this to me, perhaps it's even a setting in the OS somewhere?
Thanks.

how to turn GPRS off?

hey...
i was just wondering, is there a way to turn GPRS off?
it is really expensive and i dont wish to use it...
thanks
jay
Dear,
As in its commercialization of ppc 2003 that says "always on GPRS", we cannot easily turn it off anywhere in the GSM signal sign. The only way I've known so far is to softreset your device. There might be some other means to turn it off. Anyway, I guess it has to do with the registry setting (I'm not sure)
REgards,
well....i currently have ppc 2002
and all i want to do is disconnect it permently...
i just saw my bill and i was using Gprs when i thought i was using wap....and i get wap free.......so u get the idea :?
so i wanna know how i cannot use gprs at all, beacuse i get them confussed
thanks
jay
Disconnect GPRS
Maybe try SPB GPRS Monitor. It has a connect/disconnect feature.
so i have to download a whole piece of software to turn gprs off....
thats a bit silly

In order to end a GPRS section on PPC2003 simply press the call end key and wait till it beeps. If you press the end key again it will turn the phone off.

Thank you. Brilliant. Just tested. Works. Case closed....
I disagree...
as mentioned in this post:

The problem is bigger then just that. Personaly also mentioned it beore in this forum on the WM2003 bug list that clicking the OFF "RED" button for a while it will d/c the GPRS session is true but what you dont notice is that when the beep sound goes on call your self from another phone and you will notice that your phone for at 30sec will be "OFF" while your device shows full signal bars.
I tried that 6 times to be sure and everytime the same result: GPRS d/c - Signal full - but my phone is OFF for 30sec or so.
I should also stress that in the above posting you will find important information about GPRS "Always ON" which is important.
After ailing in any normal alternative i was forced to use Sbp GPRS monitor which is doing a great job for me.
so how can you tell when GPRS is fully off....
knowing me i will still end up on it, although i dont want too.
thanks

First, let me say I do think it's odd that there is no software route to d/c data session, however I do find it very strange that people are posting in kind of an opposite way of the solution? A little history, in the defense of the GPRS Standards Community (just do a google search for EDGE or GPRS standards and you will find their website with detailed explanations of what their technology is and their vision for data on Mobile Terminals as they hope it will be implemented) the XDA "Bug" was that it could not do what every other GPRS enabled device on the market could do at the time and that is, keep a deticated data connection and meet the definition of what GPRS as a service was. Meaning the super XDA was inferior to the simplest cell phone with GPRS (ok that's a stretch we're simply talking phone & browser functions, and yes PIE is way advanced even in it's first inception to any phone browser out there but what people were ashamed about is that the phone never did effectively what its main draw was as a combo device) basically the "Bug was it was advertised as a class B device and never was (for class B device standards do a google search for GSM Mobile Terminal class standards, class A is what we are shooting for).
I think since GPRS is expensive (for now) people who bought this device never really saw or actualized what the real gem of GPRS was other than just a faster "Dial-Up" connection which it was never intended to be viewed or treated as a Dial-Up type connection. This behavior was by Microsoft’s/HTC or both(s) design and failure on their part(s) to have this device meet the standards that every other GPRS device at market did.
Keep in mind I am not saying what should or should not make us happy as an end user, it is simply an issue of end user preference and not a Bug (the software GPRS off option missing is a big inconvenience for people who want to keep a tight grip on their data usage).
To say "GPRS-Always-On" is a bug is like telling the inventor he invented it wrong because he did not invent it the way I like it.
Keep in mind I am not arguing the missing software/hardware "option" to disconnect if you wish, but to help everyone understand what GPRS is, has been, and hopes to continue to be, and that what some are complaining about is merely a personal preference, or missing option and not a bug.
What ever an implementer of a technology charges for something should not dictate whether or not the technology behaves in the way it was intended too.
That would be like saying if gas prices were too high that manufactures of gas burning engines have a major bug on their hands until gas stations start charging less for gas.
Then it will then be a welcome solution/prior bug?
As a consumer, you have choices. Buy an electric car if you don’t want to pay the gas prices and hope enough people hold your same view and inspire the gas stations to lower their prices to get more customers, boycott the gas burning car industry and ride a bicycle around (don’t subscribe to GPRS service on your account).
But don’t say just because you want to drive around in a fast sports car (GPRS-12 cylinder verses CSD-4 cylinder) and cant afford it (or feel it's over priced), that the makers of cars that burn more gas to go fast (as intended), are in-fact not performing as they were intended to because gas prices are to high.
We all like to go fast, and get the "nice car :wink: " nod's, but
Until it becomes more cost effective to drive a high-end sports car :shock: 8) most of us will have to be patient and opt for the 4 cylinder rather than 6.
A chassis with four wheels and an engine is a car; one that goes 0-60 in under 5 is a "luxury" not a necessity. Personal Necessity always dictates how much someone is willing to spend. So the question (addressed to everyone waning over this issue),....is it truly a necessity to you right now (in which case law of supply and demand, you pay to have it now) or can you wait until the prices come down (in which case too expensive right now maybe I would just like to have a fast service that keeps me connected to the digital world 24/7. I'll use the slower for now), but laying in wait for the best of both worlds will always leave you wanting
Oh I forgot one last option if you are independently wealthy, particularly ambitious, and feel PDA makers have their head up their :shock:
You can design, manufacture, and market your own device doing what you feel people want it to do and put it into competition against the current devices 8) or the poor mans/safe business approach "reference design" :idea: give the industry what not! Tell them how to do it, let them know this IS NOT what the consumers want their device to do :!: and make a stand baby 8)
Unfotunately it has nothing to do with the device.
The networks demand that GPRS capable devices GPRS attach when they power on. In the next relesae of the GSM standards there will be a bit (two actually) that define whether the device should auto GPRS attach and/or auto activsate a GPRS connection.
Then the operator can decide what to do. It will never be a consumer's choice.
i'm no expert but wouldn't you just be able to delete the gprs connection setting out of connections to keep from using it again? with no settings it shouldn't be able to connect, right?
Yes & No.
First let's make a few distinctions. The device only see's & attaches to the GPRS node, this is not an active data session it's like standby. PPCPE2002 did this the little "G" if you had a T-Mo branded this still happened you just don't see the icon. So nothing that hasn't already been talking place.
In most cases if you don't subscribe to GPRS this is not even a concern as your device/Mobile Terminal will not even look for it.
If a "data" connection is made (Service provider device flash account info or user provided account info) you will incure data traffic costs. This is why some people are concerned about not being able to disconnect a data session when they want.
This is only a temporary concern as providers will all eventually at minimum match "unlimited data" competitors prices to keep current customers from jumping ship in mass numbers to another data provider. They will even the playing field figuring customers will not move if they can get the same price at home. Statistics show they wont so this is in your favor. Even more in your favor if they compete instead of evening, this drives prices down
hello everyone.....I'm a bit off the topic of GPRS but more into GSM monitoring. Can anyone tell me how I can track a GSM modem?

Keep using Fascinate after freezing Verizon plan?

Hey everyone, I'm currently in the Air Force and I'm getting stationed in Germany. And due to that I'm going to be freezing my Verizon account till I get back.
Now I really love this phone, and I'd like to keep using it; however, will I be out of luck without an actual service plan? I'm not talking about running it without a data plan. I mean actually no service whatsoever other than the Wifi.
Can it be done?
Can I has Wifi smartphone in Germany?
Thanks much beforehand for any help!

Umm, why couldn't you? Put the phone in airplane mode, turn wifi on/off as you please. Last I checked, the didn't ban Wifi in Europe or Germany (yet, the EU does stupid stuff sometimes)

Is it really that easy? Also, what might that limit as far as functionality of the phone other than just calls and texts?
Also, would I need to worry about accidentally turning off the Airplane mode and getting charged again, or does the phone just stop receiving service period?
Thanks much for the help and I'll feel kinds silly if it really was this easy ha.
If you froze your VZW account, you should stop receiving service entirely, and not have to worry about getting calls, 3G, etc. But I could be wrong about that, so if someone could confirm...
Also, does Germany even have CDMA towers? I thought the rest of the world was on GSM.

other countries use cdma (china and india have major carriers that do) and several others as well (peru, etc) if you go to verizon's international travel coverage you can actually see (or used to anyway) what country had what type of coverage and where on a map
however gsm is the major technology used worldwide...i dont have figures handy, but id guess its like 85/15 or something split wise
with emerging lte adoption though at some point in the future id imagine things becoming more unified...or even further split as many carriers may stick with hdspa+ rather than spend the money on lte infrastructure...who knows
i have an epic 4g that has no sevice at all and my kids use it as an ipod with
wifi work great text also as long as u have wifi.
ps i got the phone from a buddy that could not pay a bill for two phone so he suspended the line.
If you deactivate your service, the phone will attempt to connect, but won't be able to. I doubt many overseas carriers would allow data usage for roaming anyway even if airplane mode did get turned off, I'd think they probably only allow calls/texts.
Airplane mode (to save battery from frivolous radio connection attempts) + wifi. You're good.
No cdma in Germany, so no network to connect to to begin with. Verizon wont even let you use a phone in Europe without a special international roaming thing on your account anyways, so they certainly wont allow it to connect if you're suspended

I was in Germany about 3 weeks ago and I kept my phone in airplane mode and turned WIFI on and off when I wanted internet access. The problem was that I was not able to find any free WIFI - hotel, Starbuck's, etc. all charged a fee. Getting on the internet was not worth the going rate of 5 euros an hour. Your experience may be different; however, except in housing it's unlikely that you will find WIFI on base.
In the past I used an old droid as a portable device around the house. I never enabled airplane mode. I even took it on a trip with me for a media device. I got stranded in TX via buddy pass. I had to take a 27 hour bus trip home. My regular phone died. I couldn't charge the battery on the bus. So I used the droid to call Verizon to turn it on. And then turned it back off when I got home. I never had any issues with getting a data charge on my plan when I was using it as a portable. If it's deactivated in their computers I don't see how it would connect to a phone service.
I assume() that this would be the same with the Fascinate. The Fascinate is nothing more than a small handheld computer that make phone calls. Turn off the phone service and it should continue to do everything else as normal.
I would look into getting a skype account. It may even have some type of free package. You could try to make wifi calls in a pinch. I have no experience with that, but it seems like it would work. I don't know how much it would cost.

TMobile Signal Booster explained (a bit)

TMobile offers Signal Booster to take care on poor signal strength.
Just talked to TMO rep. He explained, the reason signal booster (SB) cannot be used in apartments, duplexes, condos, or townhomes there is no security is built in into it.
I.e. anybody within range can use your SB.
And if he/she makes 9-1-1 call, it might be traced back to your address. 99% it won’t, but 1% is there still. So there is a slim chance you can get unexpected police, fire dept, etc. visits and TMO don’t want to be responsible for it (obviously!).
I asked rep, why TMO won’t restrict SB to talk to registered phones only.
I can configure my WiFi access point to accept connection from selected MACs only.
SB can use IMEI, right?
He said TMO basically lends us nextivityinc product.
If I want this feature, I should suggest it to SB manufacturer
Called nextivityinc support too, talked to very nice guy Steve.
He confirmed SB neither has any built-in client devices restrictions nor they plan to add it.
As a workaround, SB coverage area can be changed easily.
SB coverage area is essentially a bubble (sphere) with radius equals distance between “WINDOW” and “COVERAGE” units with the center at “COVERAGE” unit.
That’s all. I hope, you’ll find this info useful.
To mods: I decided to put it on separate thread. If you feel it shouldn’t, please move/merge with another thread.

How many bars cell phone shows where "window unit" is?
Will be useful to know for people who cannot decide whether get one or not.

simultaneous voice and data?

I got a Photon 4g, and I wanna know if there's anyway I can have simultaneous voice/data on 3G, I know its possible over "4G" (Wimax), and I really don't wanna buy a new phone outright. Will SVDO work on the Photon anywhere?

To my knowledge this is not possible. Would be hella useful though.
only way is if "voice" if via VOIP such as google voice, skype or SIP provider.

Smartphones have so many features nowadays that it is honestly difficult for any given person to make use of every one of them. Hence, there are some features that are diamonds to some and useless to others. Just because you in particular don't have a use for said feature, it can be be extremely useful to someone else. For instance, my girlfriend now lives a good 150 miles away. So a lot of our casual conversations are done for long periods of time over our phones. Should I be focusing on our conversation? Sure. Do I also wanna check xda, read an article with her to keep the conversation rolling, maybe watch a funny YouTube clip or something? Definitely. My point is, its not a feature that is visibly useless for everyone. You just don't have a use for it.

you might have an email, or be in your car using it as the GPS with the phone on speaker or bluetooth, or wanna check an email you're talking to someone about, etc. A lotta times, when I've been on the internet with the Photon, I've missed calls, and that includes using my Strava cycling app, which simply maps where I'm going.

As others have mentioned, if you have VoIP service independently of Sprint, there's nothing to stop you from using it on your phone. You can do a complete end-run around Sprint and cobble your own adhoc SVDO-ish work-around today. Your battery life will totally suck, and you'll be paying more money for VoIP from some thirdparty provider, but you can do it. Just run the client, forward your calls to your VoIP number, and you're in business.
So, why can't SPRINT do it? Simple. The service we all call "Call Forwarding" is heinously inefficient. It was invented ~25 years ago, and only works for its intended purpose (adhoc forwarding of calls to arbitrary numbers) because there are just a few people using it at any given point in time. If EVERYBODY (or even a large plurality of Android owners) tried doing it at once, Sprint would hit a hard limit beyond which no more users serviced by a given switch could forward calls until somebody else discontinued forwarding to free up a circuit (remember, ESS voice calls are circuit-switched, regardless of any packet-switched magic that might occur at the backhaul and trunk level. You'd be amazed how much metaphorical WD-40 and duct tape still gets used behind the scenes at Sprint, Verizon, AT&T, and T-Mobile to glue 21st-century wireless and 19th-century wired phone circuits together & make wireless calls look like landline calls to the PSTN).
To implement large-scale SVDO that's cost-effective, scalable, and sustainable, Sprint has to make much bigger changes that involve their switches (enabling them to terminate calls directly to VoIP instead of relying on adhoc ESS-type call forwarding) and signaling (sending notifications via the same mechanism used now to notify the phone of incoming calls, deliver text messages, and carry Google & Apple's push notifications). That way, instead of forcing your phone to establish and maintain an EVDO or LTE connection 24/7 and use it to poll for incoming calls, it can still use the more power-efficient 1x method, and simply notify the onboard VoIP app that there's an incoming call when it happens.
At the end of the day, it's one of those cases where it's easy for nimble, tech-savvy, and highly-motivated individuals willing to spend a few days learning and experimenting to take matters into their own hands and hack something into working for themselves, but it's a much bigger job to make it viable for the unwashed masses who want it to "just work" transparently without disclaimers, gotchas, and devastated battery life. It's the same reason why iPhones don't have wimax on Sprint. Apple point blank refused to even consider implementing something where users have to toggle it manually and be aware of their connectivity options at all times to really make it work right. Think I'm kidding? Find a nontechnical Sprint customer with wimax-capable phone, and check out their 4G settings. 95 times out of 100, they'll have 4G disabled, even in cities where there's been 4G service for more than a year. They went to the Sprint store, complained about not being able to "surf the web" (WE know their phone was probably thrashing back and forth between 3G and 4G & kept spending 5-20 seconds at a time in "no network connection" limbo), the employee toggled 4G off, handed the phone back to them, and they never had any clue what the employee actually DID. They were just happy that their phone quit endlessly saying they had no internet connection. ;-)

VZW Extender?

I'm sure that this problem is not unique to me. I live in a small community with poor cell service. I have a vzw booster, it's placed in my living room. That way I get good service in my yard. The problem is that most people in my town have become aware of it. We have some really questionable people that have become quite a nuisance, the type of people who you don't want to know when you are home or not. It's really starting to bother my wife. We can't even sit in our living room anymore with the windows shades open. I know that this probably the best place to post this. Can anyone help me out with blocking numbers or something. I'd hate to have to unplug it, I've searched for the answer. But have officially given up. :'(
I mean really? I paid for it, shouldn't I be able to control access just like a router?
Unfortunately it is just extending the cell service frequencies. All the same rules apply that apply to a cell tower. I'm sure Verizon could control roaming of phones on the device, but any low level tech would probably deny the possibility. They probably just don't have a easy one click solution. But i would call them and complain. Tell them you have limited data on your home internet and you don't want the whole neighborhood using your service.
There is also the possibility that your extender could be a repeater of the closest tower to you, in which case you could never deny any phone service because it would also cut that phones service from the tower.
Good luck, please post any info you gather.

I found this in the FAQ, it may pertain to you.
Can I manage and secure access to my Network Extender?
Yes. Only the Network Extender account owner can sign in to My Verizon to manage device settings. You can set your Network Extender for Open Access or Managed Access.
Open Access allows any Verizon Wireless phone within range to use your Network Extender.
With Managed Access, you can prioritize access to your Network Extender to up to 50 Verizon Wireless callers you select. Where a compatible tower is unavailable, callers that do not appear on your Managed Access list may access the Network Extender when not in use by priority callers. All callers may access the Network Extender for emergency (E911) calls.
Also Section 2 in the manual it also mentions this.
http://support.verizonwireless.com/pdf/network_extender_user_manual.pdf
Everything I find says I can set a priority list for 50 phones, but not block. Idk
