3g sim on xda11 sim working

I am on a 3g contract and only use it for phone calls, I do not use the 3g stuff(directley as I know of) Is it possible to transfer my IMEI number to the XDA11 and will it work on the 3G network. I can then use the XDA11 and not have to carry two phones, well more like bricks but good stuff.
IMEI is harcoded into a phone and cant be changed in most cases not to mention it being illegal
if 3's sim were compatible which the newer ones are not you could use it in the xda phone though unless 3 have some odd IMEI locking on their networks
Thank you for your reply rudgear
Thank you for your reply rudgear, If it was possible could it work. Changing IMEI is legal in the uk, but not in some countries.

YES !!! youre right.... so far I know in Indonesia almost everybody can change imei ...
Hi , I don't konw about the IMEI , but I know that you can use the 3G sim card with 2G phone if the provider use another network for roaming , in this case you will use the roaming one always and you will lose the benfits of 3G.
The only reason I have a 3g phone from three is the cheap calls/conrtact I don't want the 3g stuff, it's to expensive at the moment. I think 3g link up with O2 if there is no signal on thier network. :idea: maybe it,s possible to stay on the O2 network with a 2G phone?

I have read http://wiki.xda-developers.com, this did not help, I bought a serial cable and used that with a full reset and the xda malipulator, that did not work or the xda2unlock.
the xda manipulator only work with walaby xda1 devices and some say only with some radio stacks
as far as i know you cant change the imei it's hardcoded in a chip or something and cant be altered could be wrong though but i've never heard about anybody doing it
Currently I use 3G sim card with 2G phone and it work fine but in roaming mode because the 3G company has contract with another company to serve there customers where is no 3G coverage ... however my brother signed new contract with 3G and they give him sim card but in diffrent color , The new sim card doesn't work in my phone which mean the company changed something in the new sim cards .
note : I have to use manual network in my phone then I chose the other tel co. .

[Q] Will Samsung Vibrant work in Greece ?

Hello to everyone!I'm thinking of buying an unlocked one from ebay.Do you know if it will work flawlessly in Greek telephone providers ? I mean if it is compatible with their band.
Thanks for your time!
Yes it would if it really is unlocked. I've had my Vibrant for more than 4 months now and have tried it with 3-5 local carriers all of which worked like a charm, be it on 2G or a 3G one.
What frequency does your provider use over there?
- First thing i thought when i saw the title was "Major, Epic roaming charge. BOOM!"lol

[Q] NO 3G just Edge after dropping my phone

Hello Guys,
I am so desperate and frustrated, hope you can help me!
I dropped my phone from 2 stairways height.
It was working so i didnt care, but when I came home I noticed that I had no reception!
So as I have bought the phone from Germany Amazon.com and using it in Turkey, I had no warranty (even if it said I have!!) I decided to open my SGS2 (I9100) and see if anything was loose. I lifted the pins that touched the middle housing and now I have reception for phone calls all the time thanks God!
But I have no 3G at all, what happens is that is some times shows G in the status bar but never with a + sign near it. I saw + sign only once or twice in the last couple of months.
I called my operator which is Turkcell and they said that my contract is on 3G so no chance on that side. The wierd think is that my phone works with no other SIM card than mine which is 5 years old!
Can anybody help in order to solve my problem? Is there a diagnoses tool that will help me test my SGS2 in order to find the errors?
Thanks for reading guys, I'd really appreciate some help.
Hmm I'd check my APN settings first, make sure they didn't randomly change for some reason. If that failed, I'd factory reset. If that failed I'd flash a new firmware+kernel+modem, and check my APN settings again.
If that failed I'd open it up again, disconenct and clean the antenna wire, reattach and hope for the best.
If that failed I'd suss out what is the most appropriate looking part/area of parts to replace, then replace it with either that specific part, or a pre-assembled part with the surrounding parts attached.
If that didn't work I'd list it on ebay as clearly stating the phone is damaged, outlining the problem and sell it "for parts only". Lots of people pay good money for damaged smartphones. Just make sure any sensitive data/pictures etc have been securely removed before selling it.
The problem with reception was fixed with lifting the pins that touched the middle housing but, stand by :
I think I never had 3G since I bought that phone from Germany.
I feel so stupid!
I read through more and more and I found that article:
androidforums.com/samsung-galaxy-s/258859-how-enable-850mhz-3g-network-frequency-your-samsung-i9000-galaxy-s.html
It mentioned about the modem frequencies so gave it a try.
dialed the number * # * # 1 9 7 3 2 8 6 4 0 # * # * as stated and bingo!
My modem doesnt list GSM 2100 which is the deault frequency for 3G in Turkey!
But the article doesnt mention how I can ADD GSM 2100 from the menu that dialing that number took me.
Any help with this is appreciated!
First, that article is for am i9000, which is the S1. But that's largely irrelevant because the service menu code still works.
Second, this phone doesn't get GSM 2100. Never has. It gets WCDMA/UMTS 2100. GSM is for voice and 2g, WCDMA is for 3g/HSPA. Looks like you went to the wrong option. (GSM, instead of WCDMA, like the article said.)
Third, you CAN'T add frequencies, on that menu or otherwise.
Thanks.
So why is that my phone connects with only Edge?
Can this be a hardware problem where everything else works?
Maybe these setting are wrong? Or maybe it has a SIM lock? but it works with Turkcell
Is there any manual so that I can these settings_

You said above you don't think you ever had 3g. Maybe your carrier uses 3g frequencies this phone simply doesn't receive.
For example, this phone well never get a 3g signal on T-mobile USA's network, because the phone doesn't receive 1700 UMTS/WCDMA. This is one of two required bands on AWS... Which is the band T-mobile USA uses for 3g and "4g". If your carrier uses AWS for 3g, it won't work on their network either.

No this is not possible. Turkcell is using 2100 Hz.
I have bought 3 phones from amazon.de site. The other 2 phones are working.
I have to get my settings set properly, to make sure its a faulty product, so that I can return it.
There are menu options like HSPA revision, GCF, bank selection, service domain, acquisiton order etc..
Where can I find what they have to be?

In that case, just go back to that service menu, debug screen - phone control - network control - band selection. Make sure this is selected to automatic. You can make sure all available bands for this phone are selected on in combi bands. If they're all selected on, then it sounds like it could be a hardware issue.
EDIT to add: OR it could be a modem issue. Maybe try flashing different modems?
Turn back time and don't drop it

Cant call on 4g only on 2g after imei change

Hello guys I have a S8 galaxy and it fell in the water and the board got damaged.. I had to change it with an old board from an old wrecked S8 from the store.. and I live in syria .. and in syria you cant use the phone unless you pay a fee to the government for clearance for each new phone .. and they are not giving clearance nowadays for anynew phone *war related orders* ..
So the tech store guy offered to change the imei of the new board to the old imei that I had .. in that case we can use the new board on the network..
After he changed it we had a problem that we can use 4g network for data but we cant make calls .. I can make calls on 2g network only ..
In the past whenever I wanted to make a call the phone would automatically change from 4g to 3g and make the call.. now the phone is changing from 4g to H and not making the call ..
Does anyone know what should I do ?

Question If using dual sim, can you switch, or auto-switch, between the best signal?

I've got a XQ-CT54, I guess i was wondering whether if you put two sims in (lets say one esim and one physical), would the phone switch to the other sim if it lost singal on one?
This sony help guide page; https://helpguide.sony.net/mobile/xperia-1m4/v1/en/contents/TP1000669479.html
Suggests the phone can only have one 5G sim set for data traffic, but doesnt say what happens if theres only 4G available or no signal available for that carrier/network. Would it automatically switch to the other sim, or would you have to go in to the settings and switch it over each time?
Guess i was sort of hoping/thinking how good it would be to have a main sim on one network, and then another sim on another network and it would auto switch between the two if say 5G or signal was lost on one, but im guessing it wont work like that?
Thanks!
Awesome question!
PS: Would't even mind to switch manually but the stupid icons on the top screen don't really show useful information (just those crappy 4 bars loosely related to RSSI).
i guess it should work if you disable national roaming but I have never used 2 SIMs in one phone so.....
Where I live, if you have signal than it is usually present for all 3 carriers and during field work I needed multiple devices anyway so 2 SIMs would not help at all.
