AT&T LTE

I have the North American 64gb Zenfone 2. I use AT&T's Share plan and I registered my phone in AT&T's system and it refuses to give me LTE. AT&T claims LTE is enabled on my sim but it doesn't work. When I pop in my brother's sim from an AT&T locked device I get LTE. I do not have any other AT&T locked devices in my house as I recently switched. Can anyone help please??
I am having the same kind of situation with Cricket which is owned by AT&T. My SIM had LTE with my LG Optimus G Pro but only 4G with my ZF2. It is the exact same SIM.
Im on straightalk i used a att sim with no issues on my NA asus zenfone 2, had perfect 4G(lte) signal on 06610.

If the indicater says "4g" that is LTE
OK, cool. My OGP showed LTE when it had the signal. I guess I was expecting the ZF2 to show the same.

Visit your nearest AT&T store and get the rep to delete your ZF2's IMEI from their system. If they won't allow you to, borrow someone else's phone and **get another SIM card** from them. Modifying your APN settings won't help at this point.

I think the phone only shows 4g.. My Nexus 4 (wth LTE Radio) shows LTE..
I am also using Cricket and my phone shows 4G symbol, with speedtest.net I get the 8Mbps down (Cricket caps 4g at that).
When I popped in my t-mobile sim (from the Nexus 4) it also showed 4G symbol, but i would get 26-34Mbps down (which is the 4G/LTE speed)

Not enough info. Need the phone's CID, and what 3G (UMTS) bands used by your carrier.

Call your carrier and ask them, they can answer this.
Nobody here can help you, if you don't give this simple information.

Thanks, I have called my carrier and they advised that 2100 for UMTS (3G) and 2300 LTE (4g) band is used by Airtel.

You have the Sprint version of the phone (based on CID) which should be compatible with 2100 MHz (UMTS). This phone does not support 2300 LTE, but you may already be aware of that.
Are you sure your carrier's APN info is entered correctly?
You sure 3G worked for a week? Any changes that happened that could have have changed that?
Thanks for sharing this detail, I was not aware about the 4g which you mentioned. Yes my APN is correct and i have crossed checked with my carrier as well. And yes i have used 3g for a week and after that I took another SIM from my carrier(Airtel) 4g sim and just after that my 3g stopped working.
And I have checked my new sim in another phone so it's working fantastic but not in my phone. and I have checked my brother SIM in my phone so even that sim's 3g is not working on my phone. I could not understand all of sudden what went wrong which it stopped working.

Check the APN again, and that is the currently selected, active APN. All I can think, is that inserting another SIM changed the APN.
I checked again, but still same issue. What should I do any suggestion. Or could this be a software or hardware issue how to know this. Any idea

Anyone know where to find Sm-n976f network specs?

Just got this phone (specifically for root, would never use a phone without root. If root someday becomes unavailable for all Exynos models I will go back to using the super cool HTC touch pro! ? currently using the note 10+ sm-n975f 4g (single sim) on t-mobile and whenever I am on a call the data is extremely slow. And many times when attempting to load a a web page the call will disconnect lol I read that a lot of the t-mobile used network bands were removed from the international models starting with the note 9 , I assume this is the reason why the international phone is junk here in the USA ?
I am about get rid of this junk and use my old note 8 that worked fine all this time. I just thought I would ask because I can't seem to find any answer to this question online. Does anyone know if the 5g note 10+ (sm-n976f) work properly with t-mobile?
https://www.kimovil.com/de/wo-kaufen-samsung-galaxy-note10-plus-na-256gb-5g
perhaps there you find it.
Thanks but I can not read the language and web page translation is not working using auto detect language, what language is this?
Here:
https://www.phonemore.com/specs/samsung/galaxy-note-10-plus-5g/sm-n976f/
So You have the 4g model or 5G model?
The specs for the 4G model (SM-N975F) can be found here:
https://www.samsung.com/au/smartphones/galaxy-note10/specs/
By default it will list specs for the 4G model, but if you click the sub link for the 5G model (SM-N976B) you will see it supports 5G TDD Sub6: N78(3500)
Thanks for all the help, I just put my Sim card into a dual Sim 4g model and the network works like normal again during a call it before shows H and now stays at 4g.
so either the single sim has less network capabilities or the single sim was defective?
Hello,
it is German. Just change the de to en for english.
https://www.kimovil.com/en/
i have a 4G DualSim and a 5G Note 10 plus.
Both working fine with 4G .
Cool thanks for letting me know, looks like the single sim model is not as good or mine was defective
