Im sure the phone boots on the stock rom without a sim card. Wifi usually gives you better speeds than tmos hsdap for now.
If you really need a sim card you can always buy a cheap prepaid tmobile phone at walmart or wherever and take the prepaid sim from the phone and put in your mytouch 4g. All will be well, sir

Honestly, you don't need a sim card to mess around with the phone. You can access the stock rom without a sim card and use wifi for your data. If you want to be able to place calls or text, you can walk into a t mobile store and ask to setup a prepaid account. If they ask you what phone, just say you already have a GSM phone. That'll be about 20 bucks a month. If you have att as your carrier, then you can unlock the mytouch and stick your att sim card in it.

Metro PCS uses CDMA phones so you wouldn't even be able to use it with that carrier.

4G Sim Card Needed?

Do I need a "4G sim card" to get 4G speeds or no? My current sim card is probably 1 to 2 years old. Thanks.
(I know the new sim cards have a skinnier gold contact area).

Yes, you do in fact need to use the new '4G' SIM card.
I have an extra sim laying around that has the skinny gold contacts. Is that for sure a 4G sim or not necessarily? Thanks.

Not necessarily. The MT4G came with one in the box. I suggest you use that one or go to a T-Mo store and get a new one.
I don't understand this. Why would you need a new sim card? I have my old sim card and get "4g" speeds.
The new SIM cards help decide how your phone communicates with the network.
The older generation of SIM cards have a limited capacity to connect to the 4G network. They can only connect a couple thousand times and then they will stop. You'll be able to make and receive calls and text, but Data usually stops working. You will need to replace the SIM card with a new ones that has the ability to connect to data at a higher frequency rate than the old SIM. T-Mobile started to release these newer SIMs almost a year ago, so you may be using a newer one. If you want to know if the SIM card you are currently using is 4G compatible, call into Tech Care. They can tell which kinds of SIM cards are old and new.
Again, I would recommend using the one that shipped with your MT4G.

I am still using the original SIM from when I opened my T-Mo account (approx Jun 07; crappy free flip phone). I get 4G data speeds fine (see my sig image). Did not swap SIM to use this phone.

Foreign Sim Cards

Hi,
I was just wondering what type of message to expect when you put in a foreign (Canadian provider: Rogers\Chatr, and Wind\Mobilicity) SIM card into the phone be it unlocked or not. I ordered a phone and it would not even detect the SIM card, it just said no SIM Card Emergency Calls Only. So I sent it back for a refund which is still pending approval, but the seller still claims that the phone works with US carrier SIM cards (T-Mobile, AT&T).
What do you guys think?
i have a wind mobile sim based android phone with a qualcom chipset and sim booted right into it. Pre and post rooted the phone worked just fine. Stupid question but was the sim inserted properly and was it seated correctly and titly so that it was connecting. I've never had an issue with foreign phones. I'm stateside

Yea, I even tried putting paper in there to make a tighter connection. I can't understand how the phone wouldn't recognize any of my SIMs that work perfectly in other phones, but works just fine with the US SIMs that the seller has. I think the seller is trying to scam me out of the return shipping.
Does anyone have the solution to this problem? I don't understand how the phone could work fine with US SIM cards, but not work at all with Canadian SIM cards (i.e. not even recognize that a SIM card is in the phone).

So.... You are claiming a refund for the phone because it doesn't work with canadian sim when seller says it works for us based sim??? Did the seller say anything about it working with canadian sim????
My phone with s off works with att sim on 3g, or was it 2g.....

I take it you are near the U.S. border, where about? If you're near me, we can meet up and see if it is consistent in all the myTouch 4Gs. Mine is rooted, unlocked, good screen and good eMMC. Should be the best scenario to double check.

No need to. I've seen people call in after coming from another country and have used foreign SIM cards in the phone.

This makes sense that foreign SIM cards would work, if the phone communicates through a standard GSM frequency it should work for all of them. When I had the phone I rooted it with s-OFF and I'm assuming that would unlock it even for foreign SIM cards. Anyone experienced with phones being locked to a particular country?
I want to buy another MT4G but I also want to make sure it will work in Canada first.
rooting your phone does not unlock your sim. call tmobile and tell them you would like to unlock your phone because you travel out of the US often.
I did that and after it was unlocked I was able to use my phone in Ireland with a pay as you go O2 sim card

Sorry, I forgot to add that the seller claimed to have unlocked the phone with a code. I'm just wondering if the phone could still have been locked to US providers, and if so, why would the phone still not recognize any Canadian SIMs?

Im not sure. My phone has been unlocked for awhile but I believe that if your phone is not unlocked when you put a foreign sim card in and turn it on it will ask you for the unlock code.
When you turned your phone on with your Canadian sim card in it did it tell you that your phone did not have a sim card in it, or were you just unable to get service?

Sim card compalitiblity from infuse to S3

I want to remove the SIM card from my still working Infuse and put it in my s3. The problems is that sim card in the new S3 is about half the size as the older standard Sim card. Do I have to go to the ATT store and have them program a new sim card that fits my S3 with my new number?

i used a micro SIM cutter and cut my existing SIM card to fit in, coming from my atrix. just wanted to try it. i could connect to network but could not get data. so i just activated the micro SIM it came with instead.
why didn't your phone come with a micro SIM?

They should. They may charge you the $36 'activation fee' for the new SIM.
I'm fairly certain you need a new SIM due to the GS3 being LTE, and the Infuse being HSPA+.
I just made the switch, myself, this morning...from Infuse. What a difference!!!
32gbps speeds here in NYC.

The only places that will charge you for a new sim are "authorized" sales channels, not corporate owned AT&T stores. Go into ANY corporate AT&T store and you'll have a working SIM in a few minutes, no questions asked, free of charge. They'll probably ask to play with your phone or try to sell you accessories though.

AT&T specific question

I have been with sprint for a long time and never had to mess with sim cards. I am now with att and I have a question about sim cards and activations. I have an android phone right now with att that I am going to replace with the note 2. Can I just pull the sim card from the current phone and put it in the new one? Or do I have to take it into the att store? Also does this cause an activation fee?
Moved to Networking section.
You can just switch the SIM. If it's an already activated SIM (meaning it had service in the prior phone) there should not be an activation fee.

Thanks for the info. That is what I was thinking but I wasn't sure.
Yes, one of the great things about gsm/sim cards. Easy swappable. If your current phone uses standard mini sim, you will need to cut it down to work in the note2/other newer phones that use micro sim cards.
Currently using the original note. So I don't know what kind of sim it has.

You Will need to go to the store. Note 1 has A regular sized sim and the Note 2 takes a Micro Sim you will need a smaller sim but sims are free.

Your can use a SIM cutter. No need to go-to a store. Just be careful and follow the instructions. I've used it twice on various phones.

Just insert that to any unlocked phone you want,
Our policy at at&t is if its a gsm it's possible,
No fees for device transfer since we have a SIM number as a basis of the account not the IMEI or ESN
this post is approved by the national potato safety regulation
I have changed phones before and just changed the sim from one phone to the next. I also went to att when another phone took am smaller sim and the att rep got a smaller sim and updated it and handed it to me and said have a nice day. I love att's customer service.
