Hello,
I was a Tmobile user, but i got this htc one m8 verizon version from craigslist. I popped in my Tmobile sim card and it used to work with 4g but signals kept dropping, so I rooted it and then installed viper and then still signal troubles so I got a verizon sim and everything is fine. But now after popping in the Verizon sim card, I only get 3g, I never get 4g. Other phones get 4g so its not a problem of location. Maybe i changed something which is not allowing me to use 4g. It works only on CDMA and not LTE. please help me with what to do.
Thank you
PS. i actually converted my phone to be used with Tmobile and then came back to stock again after buying Verizon sim card.

So,
I have an ATT FUZE phone and service right now and it is SIM Unlocked.
I can also install any ROM (SuperCID?) and I just flashed the rom to ATT's latest Radio/WM6.1 last week.
I'm considering switching to Verizon using the same phone because ATT reception is crap
I'm assuming I can still use the latest ATT Radio (they're all GSM right?) and won't have to reflash the radio to Verizon specific? I should just be able to get a Verizon SIM card and everything else should work straight off the bat no? I know the phone will work with the Verizon Sim.
My concerns are the data -radio wise and speed and reliability with the ATT (specific?) radio.
Thoughts?
Sprint and Verizon are both CDMA.

Well the problem is that AT&T is GSM Verizon is CDMA the phone will NOT work on the Verizon network. The only SIM cards for Verizon is for international calling not domestic and will not work in the states. Sounds like a great plan but it will NOT work. Sorry for the bad news.....
the Fuze is a GSM phone, thus it will not work on Sprint or Verizon. The CDMA version of the phone is the Sprint Touch Pro (will work on Verizon or Sprint). I would see your Fuze on ebay, and us the money to buy the Sprint Touch Pro then switch to Verizon.
DO NO BUY THE VERIZON TOUCH PRO. IT HAS LESS RAM (192mb vs Sprint's 288mb). The Verizon version of the Touch Pro is a waste of money, so make sure to get the Sprint version - you can use it on either network.
So I bought a sidekick 4g thinking I could use my at&t sim card for it and got it unlocked but have one problem. I can only get 2g at the most on my network and asked the service provider who provided me with the unlock code for a solution to this. They told me something about T-Mobile running a different network than at&t and how at&t was updating there network so that I could get 4g on my phone and how it was going to be ready before the end of this year... Is it possible to get 4g yet or any other way around this?

Nope, that person lied to you as well.
AT&T and T-Mobile have different HSPA (4G technically) bands. I think AT&T uses the 850mhz HSPA Band, while T-Mobile uses a different one. Since thats the case, your SIM Card is looking for a band that the phones modem dosent have. Thus, knocks you back to EDGE. Forever.
Hi All,
I bought a Tmobile galaxy s blaze 4g (SGH-T769) from HSN last year, it was never activated or used on tmobile. I tried to put a old at&t sim I had in it and it said sim invalid. I get the same message when I put an active Verizon sim in as well.
I used a service online for an unlock code and after following the directions it prompted for pin and it seems to be unlock after entering pin
When I insert the Verizon sim it does not display invalid but it cycles between Verizon APN and Vodaphone NL .
When I try to make a call it said not registered on network
When I put the at&t sim back into the phone, I get the not registered network but am thinking because its an old inactive sim or not?
My issue is I want to use this phone in Brazil this summer so I need it unlocked and right now I am not sure if it really is unlocked?
any ideas?

Just so I get this correctly, Verizon, even though it has a sim, is CDMA network Only. So my my only option to test is a vlid AT&T sim?
Thanks for responding
update
I used a friends at&t working sim and it worked great so the phone is unlocked. I guess the Verizon 4g lte is different frequency anyway plus for some reason I thought it was some form of GSM. lol
ALL good to go here..
thanks
Recently revived my N5 that had been sitting around due to my N6P showing some water problems in case I needed to switch phones quickly.
Well, after resetting and installing AOSP Extended, I put my T-Mobile sim in, and gets no signal. It will recognize a sim is in, but I get no service at all. I figured something could be wrong with the simreader, so I tried some other sims. Sprint sim and a Freedompop(AT&T) sim both work. I know my T-Mobile sim works, as I'm currently using it in my 6p. Anyone have any solution?
freedompop uses at&t for GSM devices and sprint for CMDA devices. it sounds like your phone is the CMDA version, and your using the sprint network with freedompop. T-mobile is a GSM network and will not work with CMDA phones.
I'm being told that my device is going to be booted off AT&T because my XZP is only running at 3G (according to at&t support engineers). I find this hard to believe.
I had some initial issues with the sim because I used the sim from an older phone, which could only do 3G, so it wasn't registered on their network as capable of anything else. The jerks in the store were of no help, and even got attitude with me about dropping my sim into a new phone to see if it would register. Luckily, I had a bud who had a brand new LTE AT&T phone, so I popped my sim in there, let it register, get access to all their new/current bands, and then I put the sim back in my XZP... lo and behold, all the capabilities were unlocked.
I have been running the at&t apn for high speed, phone started using 4g+ when the LTE rollout finally got fully deployed.
In trying to run down if AT&T is full of crap or not about kicking my phone off the network that is "only using 3G"... I came across this https://apn.gishan.net/en/apn/att/sony-xperia-xz-premium
It shows I should have a bearer of LTE, and I do not. I have 4G and all of the older network types, but no LTE. Does anyone else have this? If so, what network are you on? My phone should be current on its updates, as old as they are...
Maybe I need to drop this sim into a current gen phone again and let it register on their network?
Any ideas/feedback is appreciated.
