[Asus ROG Phone Guides, News, & Discussion] iStasis:
My Carrier Three UK support the following bands:

800mhz (4G) Band 20

1800mhz (4G) Band 3

2100mhz (3G) Band 1

i get lost between phone version A and B as both support FDD-LTE bands listed above. I dont get TD-LTE at all in my country, then what confuses me is WCDMA where i get band 1 & 3 but not 20, then TS-SCMA and CDMA and the last row i dont think is still on in the uk.

so having a look on the razer phone specs as i know it works on three uk even when bought from razer but as the stock both RP1 and RP2 this maybe in their carrier settings.

compared to the RP1 i have and RP2 and then comparing to Asus i think ill be ok but need to test the LTE/Supervoice. i dont make calls that often so need to see the impact it has but then in 15 days i could test this out once the phones setup and updated make a few calls without wifi connection at my desk at work and at my house where they are the only two places i may hit a black spot and have to rely on wifi calling but this is where LTE comes in and is required to allow me to make that call on LTE/Super Voice rather than wifi calling so that if i have to leave the room or building the call does not drop out.

this is comforting to hear though from Three UK on the page below

"Right now, all 4G Super-Voice compatible iPhones will be 4G Super-Voice enabled once the carrier settings have been installed, even if they didn't come from Three.

4G Super-Voice doesn't work on other non-Three devices yet however, even if the manufacturer has stated that it's VoLTE compatible. We're working on this, so be sure to check back for updates.

Phone not compatible?

We update this list with more phones regularly, so check back again soon."

its basically a test it and see what happens, so if i can make a decent call from home or work at that point if i find its hard to make and stay connected on the phone in a call i will have to return the device.

If its not a problem and i can make and receive a call without LTE support even if it comes later which would be nice but not needed right away i can live without it. Hey i may just even work when the carrier settings hit my phone but if people say the option is greyed out that could be the network or phone doesnt support it. However if Asus are selling the phone as LTE supported and its at the bottom of the page im leading towards its enabled by carrier settings if not then i would investigate as ASUS need to look at their settings because their technically breaking the law if their advertising it as a feature and your carrier say it will work but the phone doesnt enable it. Again if you have this issue do not throw this at ASUS without doing homework 1st as from smart phones these days its hard to see where a problem lies could be google or asus or your carrier.

If you buy from asus uk direct you get 15 days to test it and check it over so in that time you its one of the things to check and return if it doesnt for you.

It hard to just buy a phone thats not sold with a contract these days and yes even Apple phones have features that some carriers support and some dont. Look at visual voice mail as i was with o2 UK for years and got freaked out when i lost the visual voicemail feature because i moved to Three UK. where you get a txt message rather than a little icon with a number on it. small thing but a good example.
