Anyway to activate 3G? Phone won't work on AT&T's 4G LTE. Only works on 3G !
AT&T says they have an LTE problem. My phone is the only one out of 4 on the
same acct. (all LTE) that doesn't work. Crazy!
Already had a Galaxy S3 I747 that did the same thing. No VM or rec'd a few hours
later & no Texts (but if I have texts out there not rec'd., I can send myself a text & everything
comes in) all of this on 4g & sporadic receipt of calls. AT&T says its a system problem not the phone.
AT&T put the phone on 3G it works, but their system keeps tossing it back to 4g LTE! AT&T no fix for it yet.

Do you have an LTE sim card?
Check your APN setting. It should be "pta" for access point name.
At&t LTE isn't a complete network. There's only one tower in my area that is LTE. And they do have system problems that can last for days.
Good question on the SIM Card. It has no identifying markings on it, as in the old cards used to have 3G on them. It looks like the old AT&T SIM CARD. If the LTE is the smaller SIM card, the answer is no.
My Galaxy S3 had the smaller card & still had the same problems. Right now (in settings... Mobile Network type) the phone jumps from UMTS
to HSPA:11 yet my wife's S2 reads LTE & no problems. Any phones out there that have the option of turning off 4G LTE besides the IPHONE?
APN is pta & problems since NOV. but just found out end of March it is an LTE problem after I began to contact the ppl at the top of the ladder at AT&T. Techs that I spoke with don't have a clue!
What I can't figure out is why out of 4 phones on the plan, I'm the only one with problems. If it were "just" a system problem it would logically affect all phones. Yet AT&T says it's an anomally with my line.
Wondering if another phone & new number would rectify it? lol
Try sim card swapping with a phone that reaches LTE network.
I still have my Vzw note 2 and can run GSM or CDMA sim cards and have test and used it.
With the Bootloader unlocked and right ROM and change the Apn Settings.
But with the note 4 the ROMs are not made for multiple carriers anymore.
AT&T will work on here and I still had to updated APN settings a little.
I removed all others to keep it form dropping call because its jumping around to other settings.
Also turned off Lte so data will stay locked in on H and H+.
I have seen it drop data connection jumping back and forth form H,H+ and Lte.
When i place my wife VZW sim card in my Tmobile note 4 LTE kicks in and I can use it.
Signal jump on but will not connect to make a call and texting will not work.
Q::: Is there anyone already running a VZW CDMA sim card on a T-mobile note 4??
Q::: Will a sim card unlock work??
Q::: What unlocking site did use??
LTE should theoretically work, but you still would not be able to call or text because most places still rely on CDMA for the talk, text, and 3g. The Tmobile phones do not have the hardware to support it. Plus any time you would not have an LTE service, you would be out of luck since there would be nothing available for the phone to fall back to. You would also run into trouble if you needed to register the phone with VZW for any type of service as the IMEI won't be in their database and they won't allow any phones that aren't there to be officially registered with them. Not to mention other problems like being unable to update PRLs and profiles.
Ok, I have have a galaxy s4 and my sis sent me her Verizon Note 4. I put my tmobile sim card in and got the this is not verizon notification. I've read some of of the forums here about changing the apn and changed each field like users here said to, changed to global network restarted and I still get no signal. There's still an inactive verizon sim, I've heard factory reset with verizon sim then change apn then put tmobile sim in but that doesn't work either. Please help, this phone is so much better tan my tiny s4 I don't want to ditch it or switch to verizon.
So I have an ATT sim card and a Cricket sim card, both are activated. I was going to go with ATT prepaid and for the past 2 days my phone will randomly drop to 1 signal bar and then completely goes to "no service" for about 2 minutes straight with the ATT sim. I put in my Cricket sim and I have perfect service, with only drop in signal roughly once an hour. How is that? When both are on the ATT network. Is it an issue with the phone, the sim, something? I have my APN's set up properly as well.
If I had to guess, possible antenna issue, also I would try the ATT sim in a different phone.

I have a Galaxy S6 Edge from US Cellular that I just got and trying to switch it over to straight talk with no luck. The phone is unlocked, I took the sim card from my Droid Maxx and it works in the Galaxy for calls, and textremely. It will only get 3G service and constantly roaming, MMS won't work. Straight talk tech support told me it needed a new sI'm for AT&T. So after spending $70 on Activation kit, they tell me sorry ATT won't work due to lack of towers in my area. I need to use Verizon towers. So how do I factory unlock the phone to use on that network? I've tried changing access points, no luck. I have nano Sims from straight talk. PLEASE HELP!!!!!!!!!!!!!!!!!

Put the sim in you want to use, go to settings, backup and reset, and reset network settings. Then reboot. Then go to settings, mobile networks, set network mode to LTE/3G/2G. Then reboot again. Try that
Still just 3g and roaming. I'm on access point I made for straight talk (tfdata) I also don't show LTE/3/2 I have global, Lte/CDMA and lte/GSM/umts
