Hello,
I just bought a refurbished SGH-I777 which seems to be great. It came with Android 2.3.6 and Gingerbread UCKK6, if I'm not mistaken. It was locked so I rooted it to unlock it. It's now Android 2.3.4, Kernel version Siyah 2.6.35.14, Build number UCKH7. It seems to be unlocked. I tried several friends' SIM card and they all were recognized, but when I tried to use mine (a prepaid Tracfone card I was using on an old LG5000G), I'm told the USIM card is not valid and that I need to buy a valid SIM Card. I tried another prepaid Tracfone from a friend and it didn't work, either.
Are prepaid Tracfone SIM cards compatible with this unlocked unit? Or do I need to change some settings in the S2?
thanks!
Rooting and flashing custom roms doesn't unlock the phone for use with other sims. Fyi.

As you can see, I'm new to this.
After rooting the unit, I used Helroz app to unlock the phone. Tried several SIM cards and they all seemed to work, save the Tracfone prepaid ones.
Tracfones have special hardware and non-standard SIMs. You can only use a Tracfone SIM on a Tracfone phone.
Thanks, I didn't know that.
Is there any way to transfer the minutes I have left in that Tracfone SIM to a non-Tracfone card? Or am I stuck with Tracfone until I use up all those minutes?
It's a closed system. You have to use up the mins with Tracfone or just eat them as a loss.
I guess I'll use it for a while as I have over 400 minutes left.
Any tips as the best pay-as-you-go plans here in the US? I don't need a monthly plan of any sort as I really don't use the phone that much. I would need something similar to Tracfone, but compatible with my S II.
Looks like Straight Talk is compatible, but I think a monthly plan of $30 (or more) is required.
I don't know of any minute based BYOD services. Best case is a non-contract monthly plan. Simple mobile is another option, but you'll only get Edge data on an AT&T phone.

I'm running straight talk on my GS2 and getting HSPA+15 all day every day. $60 kit from their website that included SIM and one month of unlimited everything. Best purchase I ever made for my GS2!
P.S. The monthly plan is $45! Cheaper than AT&T by a long shot

Hey Everyone! Quick question.
I really want to be able to use the Galaxy S3 on AT&T but I'm definitely interested in getting a plan with my sister.
She wants the IPhone 4S and I want to be able to use my S3 using a micro-sim WITH the $10/month unlimited plan.
Problem is, we're not on AT&T currently.
How do I go about getting the $10 data plan?
Here are my ideas:
1. She gets the iPhone, I get a basic phone with the $10/month data, and then switch the SIM card out and put it in the S3. Is that possible? Or will they detect that my IMEI has been changed from an AT&T phone to an unknown phone....
Ideas?
Thanks so much.
My guess is that it's entirely possible. I'm in Australia and people do that all the time, myself included.

Do you think I just should order the SIM card instead of the phone, and then cut the SIM card down to micro-sim and just use it......
I'm not sure if these plans are available in America, but in Australia you can get sim-only plan or BYO Mobile plans. They are plans that don't come with a handset and are generally cheaper.
Also, in Australia you can simply walk into your carriers store and ask for a micro sim or regular sim. They'll swap one for you on the spot and it'll be usable by the time you walk out.
When I first got my SGS3 I used a sim cutter to cut my original sim and it did work, but the next day I went to get a proper micro sim. There was no difference in performance on either sims.

If i understand correctly, you will be getting family plan or two lines. One line is iphone 4s and other line is a dumb phone with dumb phone unlimited data plan. You then want to put the dumb phone sim in sgs3? If this is the case yes it will work with no issues.

Hi, so I currently have T-Mobile Monthly 4G with a regular sim card.
I am planning on buying the GS3 outright. Has anyone done this yet? How did you go about obtaining a micro sim-card?
I just called M4G c/service and they said to go into a t mobile store and purchase one. Problem is, when I got this 4g Plan in the first place, tmobile had no idea what it was, and the only way they could sell a sim card was to activate a phone. So I had to order it from tmobile.com...problem there is, there is no way to order a micro sim, only reg. sim.
I would hate to use a cutter. With my luck it'll split in half, or I have the bigger contact sim.
Any input would be great. Thanks!
My store cut my payg sim down so I could use it. The cutter had a paper stapler style to it. It looked painless to be honest.

1. You can cut your current normal SIMCard
2. I believe you can get one free of charge from your telephone company (I received mine for free, O2 Germany)
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?
Crazysah
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?
So I unlocked a bad ESN T-Mobile Htc one phone using a unlock code and an at&t sim. I also flashed the phone and replaced the tmobile stock with the att stock. Is it possible to get this phone to work now? Or is there no chance?
Also I first unlocked the phone then I replaced the roms.
If anyone has any clue if this could would would be a life changer! Thanks in advance.

Perhaps you should stop stealing phones. Half kidding. T-Mobile and AT&T now share the EIR lists so in theory it should not work on either.
So is there anyway to get this working on any carrier at all?
And umm, I purchased this phone on craigslist. the guy lied to me so now I'm stuck with a bad esn phone....
Nope, all the carriers share a blacklist of stolen phones. If it gets blocked on one it gets blocked on them all withing 24 hours.
Sell it on ebay. International customers will pick it up

How much do you think they will go on ebay? I am really not trying to be at too much of a loss so I hope I can get atleast 400$. the item is in mint condition.
You can get closer to 500+. Just make sure you list it as bad imei and sign up for the global shipping program ebay offers. They will take care of international shipping. Be careful when it comes to shipping to india and russia. They take a while to deliver and may get lost

have you tested this theory out? Let me know if anyone knows if straight talk can work with a bad esn phone?
In my opinion there is a HUGE loop hole, i have an AT&T HTC One I just bought today just found it has a bad ESN via swapper, but little secret, it still works perfectly fine using a previously activated sim, so your best bet, get another handset on the carrier you wish to use (GSM only) activate that handset, pop the sim card into the bad esn phone, and eureka, service and no MM#6

I don't understand how your phone still works on AT&T if it had a bad ESN. A bad ESN means the phone WON'T work on that network. So if an AT&T phone had a bad ESN, no matter what SIM card you put in it, it won't work.
But if you have it working, I wouldn't be complaining. I remember back when Tmo didn't have a no-throttle plan, I reached my 5GB, but I was still getting fast download speeds. I got the text message in all. This happened for about 3 months. Then it stopped. =.[
I'm not going to get into the details I read in this thread about carriers sharing their ESN's. That is new to me. I'll have to go read about that on my own time.
I am curious when this will actually be enforced.
I have been using a One with a bad ESN on ST AT&T LTE for several months with no issues. I know they are supposed to share the blacklist...but will they really enforce it when it could bring them extra business. I have even used a LycaMobile (TMobile reseller) sim in the phone and it works as well.
Bad thing about CL and T-Mobile is you buy a phone, it's clean, works a week or 2 and then gets blacklisted when they dont pay the bill. AT&T & Verizon dont blacklist for non payment, although they may start for people who get the phones on payment plans.
Will the sim cards sold by net10 work in the HTC One, its a verizon phone but not using verizon anymore, And if so, will I need to be unlocked?
Or does anyone have another way to get my phone working again without a contract or an expensive monthly bill, im all ears, thanks.

Yes, it'll work. The phone is already unlocked.
