A few days ago I found out that T-Mobile's 3g won't work on the Photon (only their Edge service) after I'd already ordered 2 T-Mobile pre-paid SIMs. Yesterday I received my T-Mobile pre-paid SIM cards, and sure enough, it's like being back on dial-up.
When I go to StraightTalk's website to order a SIM card and put in my zip code, it tells me that it will send me an AT&T compatible SIM card. Here's my question: Since AT&T is also GSM, will I still be stuck with 2g speeds or will I be able to get 3g? I know that both AT&T and T-Mobile have good service where I live. (Sorry if this seems like a stupid question, but I've been on CDMA for almost a decade).
Thanks in advance!

Yes, you will get 3G data speeds. I have 3G data speeds that beat Sprint's 3G speeds.
Make sure to flash the KDDI radio before doing so or you won't get any results.
tmobile is unique in that they use 1700mhz for 3G (which isnt used by any other US carrier). The photon is a quad band (not penta band) phone and doesnt pick up 1700mhz frequency. Tmobile is making a transition to put 3G on 1900mhz so that it is more iphone friendly. Some locations in the US have already made that transition.
Thanks for the help guys. I guess I'll finish out this month on T-mobile then switch to straight talk.
Hi
I just purchased a verizon galaxy s4 and I am trying to activate it for verizon prepaid service. I just talked to one of the representative on the phone and he told me galaxy s4 cannot be used for their prepaid service. Is that true? Is there any way to activate it for verizon prepaid service? Please help out a newbie... I have been searching around but I am having a hard time. I'd appreciate for help
Probably not. I have never used a prepaid phone but im guessing the reason why it's not likely is it's such a new phone. Usually only old low end phones with a stripped down OS is usually a prepaid phone.
So idk for sure but i would think a flagship phone is not able to be set up as a prepaid phone.
Also, might have something to do with the sim card or maybe the lack there of.
4G phones cannot be used with Verizon Prepaid, at this time.
ok so that's it, you have to have a sim card to use the LTE system so that means only 3g phones are the prepaid. I thought it had something to do with the lack of Sim cards.
So i was wondering has anyone tried to use the galaxy s4 on straight talk? so it would use the CDMA towers. the reason i ask is because i have been using the s3 on straight talk via Verizon towers and straight talk actually sent me a Verizon compatible sim card and literly all i have to do is take the sim card out of my s3 and put it in another galaxy s3 and it automatically transferred my number and activated on its own. so i wonder if its possible to put the sim in a Verizon s4 and use it that way.... And yes it used 4g LTE
bump???
Not including myself, the rest of my family is on Verizon. My daughter recently upgraded her S3 so I have it now as a handmedown. I have AT&T
and have been using it with their sim. (Verizon doesn't lock their smartphones) I get normal voice coverage but can't get anything more than
edge on data. I have 2 APN's programmed that I found here. One is HSPA+ and the other is for LTE. If the sim is in an AT&T phone, I get LTE
coverage but in the S3, nothing more than as mentioned. Is this because AT&T doesn't have the IMEI registered on their end or is it something else?
I'd really like to get more out of this phone. Any ideas?
Thanks ahead of time,
Todd
In the G4 forum, we realized that Verizon has put some sort of firmware on the device that disables 4G LTE in GSM mode using a T-Mobile (or AT&T for that matter) SIM card, even though the phone does support the bands. When the phone is switched to CDMA mode, then 4G LTE works fine, but unfortunately voice doesn't work at the same time. See this thread here for more details: http://forum.xda-developers.com/verizon-g4/help/lg-g4-vs986-t-mobile-lte-problem-t3195888
Can anybody try out the same with the V10 and report back? Would be intersting to know if Verizon now intentionally started crippling these devices (since it used to work fine on the G3), or this is some sort of bug that only applies to the G4 right now. Thanks!!
I use a VZW branded V10 with my tmo sim and can only get H or H+. Rarely does it get 4gLTE. And when it does sms does not work.
Thanks... but you do get 4G LTE sometimes when in GSM mode?!?
Can you change the system mode in the mobile settings to CDMA and check if it gets 4G LTE with the T-Mobile SIM card? And then in the same place switch it back to GSM and see if it falls back to H+ only? That's the behavior we saw on the G4, like Verizon is intentionally blocking LTE om GSM, even though the phone supports the band.

I am not sure if it is the same with Tmobile, but when trying to use a Tmobile variant on AT&T, LTE does not work either. It seems that you have to get the device provisioned by the carrier for LTE using it's IMEI, not just doing a SIM swap.

Yeah if i switch to CDMA, i get 4G LTE very often though i cannot send message or call
Can anyone tell me if u get the annoying unauthorized sim card message... if so can we stop it from appearing. Had that issue with my verizon htc m8.
I tried at a T-Mobile store earlier to see if one of their Sim cards would work in my VZW V10 and I had the same issues.
The pop up saying "not a Verizon Sim" or whatever came up after a few minutes of dismissing it as well.
When it first loaded up, I changed the APN to match the in-store display V10 with its exact settings. I changed the network mode from global to LTE/GSM and after a minute it showed it was connected with 4G LTE, but it went away after a few seconds. I couldn't get it to come back, and it only had like 2-3 bars, and H for data. I know it wasn't from lack of signal because the display V10 had full bars with LTE.
I also tried sending a text using the T-Mobile SIM to one of my other numbers, but it didn't go through at all. Didn't try placing a call, but regardless it didn't seem like it would be worth it to switch.
No 4g LTE
Still waiting for a fix,can get no 4g LTE on t mobile,I'm on marsmallow so I lost root access
I'm Canadian, I just bought an unlocked Verizon V10 on ebay and I'm planning to use it on a Canadian carrier. Does this mean I should expect to have no LTE data at all on this phone in Canada? Poops I never would have bought it if that was the case.
Let me know, I may try a return without opening the package.
how different is the speed between HSPA+ and LTE? is it noticeable
does it bother you that its not LTE?
I bought a phone from a seller on swappa. when he listed it. the phone had a clean ESN.
took it to the verizon store to setup verizon prepaid and it was flagged a non pay account
cannot activate.
I am using my ATT sim card right now
I can return it but on the secondary market is many LGV10 phones are going to be flagged for non payment when the accounts go into collections, it then buyers could get screwed.
I might just stick with the phone. But i can never use it on verizon. I have to wait for a Root on marshmallow, and fix after that if I want LTE speeds on ATT or TMO
I got LTE working. In happy with it. I think the US phones work in Canada even with a bad imei.
Another area on a long long laundry list where canada is better than the usa. hockey and standardized healthcare being 1 and 2... hahaha
I was having the same issue on my Verizon v10 vs990 on my T-Mobile network. I went into the APN settings and set it to LTE/CDMA and it works perfectly. Calls, SMS and data.
