I recently unlocked a samsung infuse for myself.if you ask why,i had a rooted htc hd2 with android on it for two years, changed something on my plan and I'm not able to upgrade for another year I got tired of my phone and tmobile had nothing interesting to get. Anyway lol I unlocked the infuse for tmobile and the phone is stuck on edge and it won't switch to 3g/4g.i asked tmobile how to switched they said any unlocked non tmobile phones stay on edge.I'm coming here to guys to se if there is a way around this. I tried the*#*#4636#*#*, it wouldn't accept the changes. Please if anyone knows how to fix this let me know. Also one more thing for some reason I'm not able to send text messages but I was able to send them a day ago but not anymore. I am still able to receive them, any info on that would help also. Thanx everyone.
First of all you cant use the hspa+ with a tmobile sim cuz they dont use the same bands and for the text messages go to messages and press the menu buttom and the message center and fill it with the t mobile message center numer

It sounds like you got your text issues solved, but as far as being limited to EDGE - Sorry, there is NO way around this. It's a fundamental limitation of the radio hardware in the phone. NO AT&T phones support T-Mobile's 1700 MHz AWS 3G band. A tiny handful of T-Mobile phones support the AT&T 3G bands but not the other way around.
Well thank you for your input guys. The text problem issue is solved, but there is a catch. I noticed when I shut my phone off when I go to sleep or to reboot, I have to keep entering the message center number. If not I keep having that problem with text messaging. Anyway to solve that issue?

Hey guys, im hoping someone can help me out. I also used to be a TMO HTC HD2 user but my screen broke and I couldn't fix it so I got an Infuse hoping to unlock it but after I did so I still had problems. The phone wouldn't let me choose the network operator so I flashed a few roms and am now on the Infused 2.2 rom but I still cannot make any calls. Can anyone help me out? Thanks in advance.
Is it possible I bought a simlocked I9020A? Works fine on at&t but my tmo simcard wont work at all (no edge). I got it off craigslist but did a factory reset, so figured anythng the previously owner did should be undone.
Aren't all GSM Nexus devices unlocked by default, only difference being GSM/3G frequencies?
So why did you buy an att nexus s when you have T-Mobile?

If you're able to make calls with the tmo sim then it is already sim unlocked. Though I am not sure why you're not getting edge.
Btw, is it rooted?

yeat I thought I'd at least get edge with a Tmo sim in. I use ATT in the US, the Tmo sim is my womans and was just to test it since since we are traveling to Europe in two weeks.
It won't hurt to check your IMEI and /efs
Sorry, didn't see that it works on AT&T :/
You should get Edge at least. Guess there's something wrong somewhere else. Talk to your carrier. If you can use some features it's not simlocked at least.

I would try adding a tmo apn. Not sure if it'll work but worth a shot.

I have the same problem, but the other way around. I have an I9020T which does not seem to work at all with AT&T. I've made many phone calls to Tmobile, to AT&T, and to Samsung's tech support. I haven't found a resolution, yet. The last thing that was told to me by the AT&T tech support person this evening, was that perhaps I need a newer simcard - one that is fully compatible with this newer model of phone.
I'm also prepared for the possibility that the phone has a hardware defect, however I don't want to send it in for an RMA until I'm absolutely certain.
Samsung (after checking my IMEI) has told me that the phone is definitely sim-unlocked and usable on any carrier.
A couple helpful hints when talking to any tech support person:
Make sure that they cross check your IMEI number. They have a database, and if they can establish some facts about your phone that way, it can really expedite the process.
Also, be aware that tech support people step through flow charts with you, and they usually aren't actually very technically savvy. If you can get them started on a constructive tack - they'll find the right flow chart, and you might get a lot more help than if you simply call up and say "it doesn't work."
In this thread, i do not ask for any help with any flashing to other carriers. I only have a question about it
Donor: Samsung Prevail
Phone to be flashed: nS4G
So i got a used NS4G from a friend. It has his number on it
My question is...if I flash it, will I have to take the phone to sprint to get the numbers changed? or will the number change to my donor number when I flash it? oR WILL a new number appear?
by the way my donor is activated and was used before
:banghead:
Be careful. What you're talking about doing is a felony and you seem to have no idea what you're getting into.
Good luck

Not to be rude but if your title is more specific, e.g. with NS4G in it, maybe there wouldn't be that many viewers. I thought it would be something I could help with, but I'm not familiar with CDMA networks. I used to be on Sprint once upon a time, and I remember I had to take the phone to the Sprint store to have them activate my number on it. Goodluck!
This may work but u 1st need to get the MSL code for the ns4g. Try the app called "get my msl" . U need this code to call sprint. Just say ur buddy had sprint and he gave u the phone.
When u call they will have u enter the phone prompt commands so be on a stock ROM so they work and it will match what they see in their monitor.
This is compared to actually having an old phone that u wanted to switching to ur number.
Now they may catch on or say that the phone was never a sprint phone since the ESN # behind battery isn't in their system. So hopefully they don't bring that up.. then ur good just as long as u did the flashing correct.
Good luck
Vs Nexus S 4G

Felony? How about the carriers give users the ability to move a phone from one cdma network to another just like GSM phones are capable of. Is unlocking a simlocked GSM a felony also?
What should be a felony is having a user buy into an expensive 2 year contract by spending $299 on a phone made in China for $180 cost and not letting you use it anywhere but their network even after the contract.

Its sad you have to go through such measures just to get a decent phone without paying an arm and a leg for it. But to answer your question if I understand correctly, one you flash it and use the donor phone on ns4g it will look like the donor phone to sprint or other cdma carrier on the network. So the old number should no longer matter and the ns4g should register the Samsung Prevail number.
OK thanks for the help

I got my NS4G flashed to boost, it is actually more than a simple flash, the ESN is changed to that of the donor phone. So sprint will always see it as the prevail. Just remember the prevail can never be used again without changing that ESN also.

Oh so I dont need to do so much to get it switched? only the esn? SO I can use shrinkage and use 3g on the boost mobile network
also, i cant seem to get the com port of my ns4g. can you help. I can find it in device manager with the drivers installed
You need to have your NS4G connected as USB modem.
my 10c on the matter - the number is tied to the SIM card you are using. No matter what you flash, you can't change that. My advice - do not play with this type of things, you'll get your phone locked up and from there on it's all downhill

He's talking about cdma phone. Flashing to other carriers is done ONLY on cdma networks for one reason and one reason only... they don't have sims.
LTE might change that but not yet.
CooLoser Tech: PM me if you still need help.
I'm fine I did it already. Thanks anyway

Hey guys, I am using Simple Mobile because they have a decent unlimited everything plan but i cannot get 3g. It is odd because my phone is an unlocked T mobile version of the galaxy s1 plus. Simple Mobile uses Mobile.
At any rate, is there a comparable carrier that would give me 3g with unlimited everything?
I am in the USA btw.
Is there any chance i am doing something wrong with set up? Why would a TMobile version not get 3g with Tmobile?
One more question. My phone says TMobile but it is unlocked. I can use it with any sim card? right?
So sorry for all the questions.
Thanks for the help,
Richie

You should be getting 3G with your T-Mobile branded phone, maybe you didn't set up the proper APN's. Follow the link below and find your phone, enter the correct APN's if you havent already. Your T-Mobile phone shouldn't need to be unlocked in order to use it under Simple Mobile, but since it is unlocked, you can use it on any GSM carrier around the world. Speeds might vary depending on the frequency.

Yeah, i did that when i first got the sim. My phone doesnt have the frequency for 3g but it just seems odd because it is a t-mobile phone. I am not sure if it is a problem with simple or t-mobile.
Thanks for you reply,

This weekend i will finally get my HTC sensation. But it was carrier locked so the guy unlocked it before he wanted to sell it to me.
Now he has "no service" always on all SIM cards tested.
The unlock method he used is unknown for me, but i think i can get that information out of him.
He tried:
-3 or more different custom roms
-returning to stock completely
-some more if i get information out of him
So, my question is, what is a good fix for this? (Sorry if i didn't give you enough information, but i can get more)
Also sorry if someone already posted this with similar problem.

Sounds like the IMEI has been blocked, usually due to the phone being reported lost, stolen or a service contract breach. This is different to SIM unlocking and can't be undone as the block is applied from the service network side, not on the handset.
It can be used as a pda with wifi but the phone & mobile data will never work again, unless you can find out why the block was applied and get it rescinded.
This may be a stupid question but the imi number, is it blocked on the carrier he is using or are imi bans for all carriers?
