Phone blocked from using other SIM cards? - Android Q&A, Help & Troubleshooting

Hello. I have bought a phone from one of the carriers in my country (they're everything, internet service providers, telephony-telecommunication for whole country, etc). I pay off that phone monthly, for a year, when my contract ends. With a phone I got a new phone number, their SIM card. Now, if I am to put another SIM card (another phone number) into my phone, it just doesn't recognize it, doesn't allow me to use that phone number, it acts as if SIM is not inside. (even if the SIM is from their own network)
So, I guess they did something to a phone, they limited him (blocked him somehow) so I can use only this provided SIM card from them, until my contract ends. I guess it's their way of insurance that I will pay the phone fully by the end of the contract. Anyone knows what exactly and how they did it? Is there a way to bypass this, like root the phone or something, so that I'm able to use another SIM cards aswell?
Phone is HTC ONE M9.

[Q] ESN Swap?

So, I ordered my Thunderbolt on a secondary line, (used its upgrade) and it will ship that way, with the SIM card not inserted yet.
I've read only one thread on AC forums stating that the SIM card gets activated when you turn the phone on initially, and then is permanently associated with that phone line (in this case, the secondary line).
I was curious as to ESN swapping the Thunderbolt to my primary line, but the thread also stated that I would have to get a new SIM card.
If I were to ESN swap BEFORE I put the SIM card into the Thunderbolt, would the SIM card be then associated with my Primary line? Or is the SIM card already shipped with data/information specifically for my secondary line?
ESN Swapping I'm pretty sure is 100% against the law and no one here will help you do that.
That being said, just activate it on that line and get a new sim, and then activate on your other, or call them to see if they can switch the ESN for you to be associated with your main line.
ESN swapping as in swapping the Phone with ESN #### on seconday linke with phone on the main line. Not against the law I do it with every single upgrade I do on my sub lines. VZW website and customer support is setup todo this.
In fact I got my ThunderBolt through the store, upgraded on a seconday line, then put it on my main line. I'm not sure what they did, because I was not the one who picked up the phone.
As far as the SIM card, I'd bring both phones into VZW store and have them do it for you. VZW is having a really hard time with this 4G phone launch. It may work if u do the ESN swap before the phone is turned on, it may not and u might get screwed. Doing it with the VZW Tech will ensure that its done right

[Q] OT: O2 SIM/topup, PAYG

Hi there,
Figure there are lots of people like me who bought the SGS2 from O2 but are using it on a different network. As I wasn't an existing PAYG customer on O2 I've ended up with a SIM and £10 credit which I don't need.
Does anyone know if it's possible to give the credit to someone who is on O2 PAYG? Or has it already been added to the number associated with the SIM? I've done nothing at my end, not even opened the package the SIM is in.
Thanks!
You cannot transfer credit, just use it up on calls or enter the gadget show competition 6 times. lol
The only way is to give the person the SIM as far as I know. It's associated with the number.
If the sim has not been activated then sell it .
If the sim has been activated then it can be used in any unlocked phone .
SGS 1 i used PAYG sim in phone one week passed on to my brother different phone he used most of the credit on internet data . I used the remaining credit to set up New SGS2 .
The number remains with the sim .

Quick Question

Hello,
So before today I was on the $50 unlimited plan on prepaid, which I filled up every month and I had never bought a phone from T-Mobile.
Today, I went in to buy the HTC One and I said I wanted the phone outright. They checked my account and said I am qualified. They also said that I can only do it with the $70 plan. Is this true? How do I change back to the $50 plan?
Also, they said 90-days for unlock. Is this true or can I do it before?

Also, they made it seem like I am now on postpaid instead of prepaid?
Can someone help shed light on this?
Sounds like the in-store people just f'd you over and changed you to postpaid without telling you. You'll probably have to get on the phone with customer service and fight with them for a while.
As for the unlock thing, there are tons of sites that will provide SIM unlock codes for a fee (usually like $10-$20), or T-Mobile will give people whose accounts are in good standing (or something) the code after 90 days. But I think you might be confused between SIM unlock and bootloader unlock. If you want to take your phone and use it on AT&T or in another country's network, you need SIM unlock. If you want to root and install custom ROMs, you need bootloader unlock. You can unlock your bootloader whenever you want from HTCdev for free.
Yeah, I'm talking about SIM unlock only. I need that as I live in India 4 months of the year. Is there anyway to change from postpaid back to prepaid? I don't want to be on postpaid at all. They said there was no other way I could buy the phone. I want the $50 plan (not the $70 one they put me on!)
He jagged you big time bro... But fear not!
If you haven't activated the sim on the plan yet then all you gotta do is call 611 T-Mobile from your PREPAID sim and tell them to active the other sim for you. Your number/plan will transfer over just fine.
If you already switched plans then you will need to buy another sim and do the above
Simple eh?

So, when I call them what do I tell them? He said that the SIM he put into the HTC One has a temporary number and either that SIM or the SIM in my current phone (HTC Explorer) will get a message saying it is activated. I haven't gotten any message now. So what can I do?
At the moment, my HTC Explorer with current SIM is still working and the new one is temporary but I think still working.

It seems that the card is already activated. You cant just deactivate a card and reactivate it. Once deactivated you cant reactivate it, EVER.
Youll need to deactivate it to go from post to prepaid. You will need a new micr-sim and either:
1) slip it in the phone and it will work
if this doesnt work then there is step 2
2) call 611 from prepaid phone and tell them you want to transfer your number to other new sim. They will ask you for sim #. DONE!
As for this other plan they activated.. ask the prepaid person to transfer you over to post-paid customer service and talk to them about deleting that account. They cant do it, but they can refund you the money and let it not charge you ever again (if already charged)
All these steps should work so long as you paid for the phone in full. If not, you are bound by the terms/conditions to keep the post-paid account or to pay the phone off in full to get pre-paid.
I called them up and they just switched my account from postpaid to prepaid, gave me an unlock code and also activated Wifi calling for me. It was as easy as asking them to do it. The customer care was super helpful. I haven't received any of the confirmation emails they said they would send but I think I'm all good.
Anything else I need to be worried about?

[Q] Compromised at&t SIM card?

Sorry for the length, but proper context seems necessary. Normally when you activate a phone at AT&T they give you the card that the SIM was punched out of, right? When I bought my S4 a couple of months ago, they gave me the card. I also asked around and other people I know say that they were also given the card (the credit-card sized card that the sim is punched from) when activating through at&t. Well, I went to at&t the other day to have another phone activated (an iPhone). I wasn't signing a contract or anything, just activating another phone on my account. They had no problem adding another line to my account but there was an issue that prevented the sales rep from activating the sim card. He kept trying and trying and it just wouldn't work. For some reason, it needed a manager and not just a floor manager but a store manager. After trying multiple times, I had to wait for a manager to come and activate the sim from a computer terminal (rather than the iPads which are normally used). I was told this problem is rare but happens from time to time (with a fake smile). Anyway, after activating the sim card, the manager waived the $35 activation fee (awesome!). I was all set to go, activated phone in hand and I went to grab the card that the SIM was punched from, but the manager quickly grabbed it and told me "No, these don't go to customers -they get shredded. As a matter of fact, I'll go shred it now," and she carried it off back to her office. I wasn't persistent or anything. Now I'm not a paranoid person but I just got a gut feeling that something was amiss in how that was handled. My gut told me something wasn't right. So I have a couple of questions:
1.) Is at&t now shredding all of the cards that the SIMs are punched from (with all of the info) instead of giving them to the customer? Is that normal at&t procedure to shred the SIM punch-out cards? It would seem like a logistical nightmare to be SOP.
2.) Can any kind of fraud or surveillance result from someone having that card? Am I in danger from fraud or extra-surveillance (from local authorities, as opposed to the all-sweeping NSA) for instance?
3.) Is this normal at&t procedure? Should I be suspicious, or even worried?
Input from anyone with knowledge on the subject would be greatly appreciated. Thanks.

ATT US activation

I'm planning to buy the z5 compact. Either on eBay or Clove or handtec.
I plan to get att in the us either the share 2gb plan or the 4gb prepaid. Not sure the diff.
Anyways, on the site, when I click "bring my own phone", it asks for the imei, then the mfr model. But there are no Sony phones. What do I choose?
Also I've never bought a phone online and brought my own phone to a carrier before so any tips would be welcome
Well I can tell you the what I did for T-mobile, If your using a prepaid plan, which is what I did, I shouldnt be any different. I bought the Nano Sim Card For my Carrier, Which your looking to get an ATT NANO Sim Card, AT-T-GoPhone-Nano-SIM-Card-with-Standard-and-Micro-SIM-Adapters is what your looking for you can get them at walmart Then get your plan Card. Put the nano sim card in your Z5 compact, located on the side under neath the flap, there is going to be a Black nano sim card holder, ITS TINY, and hard to see, Its smaller then the mirco sd card slots below it. Place the sim card with the gold side facing you. Put the sim card with the holder in your phone. Turn on your phone, and follow At&t activation steps. Then they are going to ask for the Prepaid Plan code, Type it in. Bam you have service, If data doesnt work then you have to call and get the UPDATED API information. or wait a couple of hours
I guess I have done some of that before. When traveling intl, I have bought sim cards and installed them. APN download is usually automatic.
I've never bought a phone from another country and tried to activate it on AT&T. I assume I can buy from anywhere as long as it is (carrier) unlocked. AT&T asks what kind of phone I have in order to send me a sim card. This one isnt on the list. Which should I choose?
