Looking at the user's manual for the HTC One S (for T-Mobile) on page 174,
I had the E ICON for EDGE data.
Also possible is G for GPRS and H for HSDPA, and 3G for 3G.
I am getting alot of entertainment for a $1 SIM card.
Thanks for the detailed progress report! I need to read up more and try a few things but:
Just FYI I activated with "pay as you go 2G Data".. I added a $10 Tmobile topup.. It is $2 per day for this, only on days you use it. I used up my 1 day which ate up the free money on the sim, and now I should have 5 testing days left. I have not gotten any data transfer to work yet though.
I did another T-Mobile test.
I sent a text to my son, and he responded with a text.
I get Edge data connection.
I don't know if I only get edge because I am on a prepaid voice/text plan, or the phone can't do HPSA, or if it is my location.
I also don't know if my doing boitloader SIMLOCK with the special config.dat file to unlock the sim card had anything to do with my success.
After much searching with Google I found good radio specs for the rezound
I suspect T-Mobile may be using hspa frequency that the rezound does not support.
Hey I thought i would update this thread since I started it. I finally got around to flashing the 'Global RUU' by going here [Exclusive Download] Full RUU Build 4.03.605.2 For The HTC Rezound and following the instructions.
I am non-rooted, not s-off.. just totally stock.. Downloaded the zip, updated it per the instructions, and restored all my apps (what a pain). It does completely wipe the phone. Wish there was a way to get around that.
So after that, I set it to GSM/UMTS mode, I put in the t-mobile SIM, and it came up with the unrecognized sim warning. SMS outbound and inbound works fine, calls work fine. I had to go into the APN's and create a new one for tmobile, all I set was apn field to "wap.voicestream.com"... After that I was on Edge and it works perfectly!
So this is good news for an upcoming trip through europe where I would like to buy a SIM and get data. I was unable to do better than edge, but really for me that is OK... Just need basic data and that's really it. Thanks so much for doing your test earlier, it really confirmed to me that the global RUU was all I needed.
Only thing: After going back to CMDA/LTE mode, putting in the Verizon LTE SIM, and rebooting, the phone did not have 3g/4g at all. I had to go manually create the Verizon APN, even if i tried to reset to default it didn't work. Fortunaley I took screenshots of my APN settings before I started on this.
I'm attaching them here in case anyone else gets into similar trouble. Thanks again!

Yes, when I tested with a tmobile simple card, I found it mandatory before putting back in the Verizon sim card to:
Keep the tmobile sim card in the phone,
Switch to lte
Examine the Verizon apn and make any changes necessary for it to be correct for vzw.
Then I'd power off the phone.
The reason is that one can not modify the Verizon apn when a Verizon sim card is in the phone.
Somehow I found making apn changes with the tmobile sim affected the Verizon apn.
I only got edge because I didn't pay for a data plan and edge is necessary for texting to work. Or, maybe I can't get faster data where I live.
Just one last update, I actually got to use the Global RUU firmware in Europe. I was traveling two weeks. In Denmark I bought a super-cheap "lebara" sim card for about $6 that had about 100 SMS messages and 10 minutes of credit on it. I used this to contact a colleague I had to meet up with. Then after a few more countries, in London I bought a "3 Networks" SIM card for 15 UK Pounds that had unlimited data, 300 minutes, and 3000 SMS. This worked great and I used it in london, manchester, edinburgh (scotland) and everywhere in between. It often had "H" in the display, and the speed was very fast. It would fall back to 3G. I had no problem transfering large files and staying in constant contact.
Only problem is over there, you can't buy SIM cards that work in multiple countries and I moved countries every day or two. Each SIM worked fine in the country it was purchased, but was stuck on roaming (and basically disabled) in any other country. In order to roam you have to have a real billing address and I would have probably had to buy a tmobile or vodafone card in the states with some credit before going over. In any case the Rezound worked perfectly and jumped right back on 4G LTE when I put in the sim card after landing in the US.
So did you get a new phone number with each SIM card?
Yup.. new weird euro phone number with each sim card... But once data connects, all my same google stuff works (gtalk, gmail, email, latitude, facebook, G+, Google voice). I never use my phone for voice in the US so it wasn't a big deal for me to have a different number..
Also minutes of talk time to anywhere outside the country you am in are very expensive.. whereas data is the same price no matter which country it goes to.
Going to Chile and would like to take my Rezound and get a SIM either before I go, or when I get there. Been doing a lot of reading and there are so many different answers out there ranging from just pop the sim in and it works, to changing APN and switching to GSM via LTE on/off apps. I am bone stock ICS, I only need a weeks worth of voice while I'm there. Can anybody confirm that its as easy as installing a GSM SIM or what other steps are needed?
