Sorry. I rarely use txt & MMS. I pretty much use Hangouts and Viber to chat with everyone I know.
By the way, if touch tone DTMF is not working, try to change the DTMF from Short to Long in Phone settings.

I have a T-Mobile edge and edge plus, both have band 12. One of the offices i work at only gets band 12.

Ofc the tmo S6 has band 12 support. I meant the verizon S6.

It's the same one that's everywhere online for TMO LTE, it's not device specific, in fact the same settings are used for all LTE enabled phones, even iPhones. I'd be shocked if it wasn't either the 1st or 2nd result after a Google search.

I once had Verizon Edge+, and used it on T-Mobile.
Add and use the following APN.
Name t-mobile US
apn
fast.-tmobile.com
mmsc http://mms.msg.eng.t-mobile/mms/wapenc
apn type default,supl,mms
Leave all other settings as is.
For MMS to work, make sure you add "mms" in APN Type field.
Moreover, once in a while, you'll get an annoying popup saying that the sim card is not Verizon etc. If rooted, just use Titanium Backup and freeze the "activation" apk. If not rooted, use Package Disabler Pro, and the disable the aforementioned apk.
Good luck.

the issue is in you are using Verizon S6 Edge+ on Tmobile network, you can't use data while on phone call.
it doesn't pickup band 12, only works on band 4 etc, which loose the data if phone call picked up.'
is there any way around?

My note 3 did this going from verizon to tmobile. A workaround i found was to switch the network settings from 4g or global to 3g or 2g only and then make the call. Touch tone would work, then after hanging up switch network settings back to 4g or global. Hope this helps you.

Not data connection in Canada, help!

HI there,
I brought my Robin to Toronto in July, but couldn't get data service however I tried. I did some brief googling on this, and found no answer. The 2G voice and SMS worked fine.
I have never had data problem in Canada in the past. I am on T-Mobile and previously LG V20, IPhone SE, Moto G4 Play, Galaxy S3, S4, S7 all worked fine in Toronto.
(trust me I tried all mobile setting options being an amateur android user for many years)
Any suggestions (other than APN setting etc that is user available in mobile data setting)?
Thanks!

Robin supports
GSM 850/900/1800/1900
HSPA 850/900/1700/1800/1900/2100
LTE Bands 1/2/3/4/5/7/8/12/17/19/20/28
Check which band your device is connecting to when you use your T-Mobile SIM.
There are many diagnostic codes but most are disabled for users to invoke.
But this one usually works,
Use *#*#4636#*#* > phone information > network type that is the band you are connected to.
If you aren't able to get info of the band you are connected to try apps like LTE Discovery or NetMonitor Cell Signal Logging.
LTE Band numbers are associated to certain frequency. Check [here](https://en.wikipedia.org/wiki/LTE_frequency_bands)
If the band you are connected to is indeed 3G/4G supported go to your carrier and ask them to get this working. Carriers usually have a whitelist of 4G devices which is how they determine which SIM is connected to which device and which network to provide.

Useful tip for switching LTE bands in the G710EAW (and possibly other versions)

If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.
Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.
This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.

I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?

I'm waiting for my RN8Pro. Is there signal strength issue by default?

You can change this in network settings menu the normal people way and also allowing only GSM will relegate you to 2g network that has indeed better signal but will kill your internet speeds.

A little bit I think. At my house, with Redmi note 7 I have 4G+ ,with Redmi note 8 pro I don't have 4G+ so often and on places that I have it with Redmi note 7

How to increase the sharpness of incoming call voice? Most of the time, voice is muffled.

The incoming voice leaks from the back of the front speaker too

how to increase the volume of the headphone and speaker?

I try this.. when I change LTE/UMTS auto to GSM only I loose 4G and have only H+ that is slower than 4G.. and the signal is the same.. I try it on one spot for half an hour

2G has almost everywhere coverage and it's too old technology to use.
When UE is registered to 2G network it can't handle voice+data transmission simultanously (most networks does not support DTM technology).
Also 2G is not designed to used AMR-WB voice codec, only simple AMR which sounds like **** to be honest.
So this tutorial is pointless, sacrifice better data speed for rubbish voice and ultra slow data speed

Redmi NOte 8 Pro has big problems with LTE 4G + tape management. The phone does not keep the 4G + it switches and stays in 4G all the time. It's a modem management problem that does not support the double-banding needed for 4G +.
Bests Regards

Xiaomi Redmi Note 8 Pro model M1906G7I (Global) doesn't connect to 4G LTE
Hi there! My problem is even worse than this you are sharing with us. I bought a Xiaomi Redmi Note 8 Pro model M1906G7I (Global). However, there is a lie about it, the specifications indicate that about networks it works for the following 4G LTE bands: B1/B2/B3/B4/B5/B7/B8/B20/B28, but it is not true as it only works for B1/B3/B5/B8/B40/B41 (I found it out by entering to engineer mode *#*#3646633#*#*). Therefore, in my case I can only connect to 3G because my service carrier uses B4 (1700 mhz, 2100 mhz) for 4G LTE. Besides that, everything is fine with the phone. What I am trying to find out is whether it is possible to activate or unlock the B4 band so that it can connect to 4G LTE. If anybody knows about a solution to this issue, I would appreciate the assistance to this matter.

Hi,
You don't have the global version M1906G7G
Global : B1/B2/B3/B4/B5/B7/B8/B20/B28/B38/B40
China : B1/B3/B5/B8/B34/B38/B39/B40/B41
India : B1/B3/B5/B8/B40/B41
You must get a refund if you bought the global version, and change to the M1906G7G to be able to use B4 .

I just tried this on my note 8t. Switched to GSM only and immediately even before restarting the phone, went from 1 bar to full bars. Speed tests show much more bandwidth available (now at 11.8mbps/3.1mbps). Sweet. First post I found after a search and first solution just flat out worked. Still think I should be getting higher speeds (I don't think I have ever really cared about the mobile speed because I am almost always on wifi, and do not recall ever doing a speed test, but at least it's better than it was now.

Question Problem to use Motorola Edge X30 in USA

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks

I have MOTO EDGE x30 with T-Mobile. Work perfectly. Check the SIM setting.

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?

I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.

you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.

Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
