I'm getting better reception, but I'm in NY. I didn't use the old SIM card because this phone is the only one capable of using MIMO in T-Mobile Network. I decided to use the SIM card that came with the phone. It's recommended for you to be able to use WiFi Calling.

If I understand correctly what I was told, there is a bug between the Wi-Fi calling to preferred calling method, AND an issue with the fast.tmobile apn. If you switch Wi-Fi calling off and change it to the 2G/3G setting, the phone SHOULD go to the the 4G (HPSA) mode for whatever reason and work.
It's there some other work around I've missed? I'm a noob so go easy on me. Lol

Network issues

Is anyone else having issues where the network keeps dropping or not connecting to 3g some times?
Nope I have a G1, so does my wife. and if I set her g1 next to my nexus one g1 will have 3g and nexus will have edge. We have very weak 3g coverage at our house. Then at work where I only get edge I do the same thing,m and my edge keeps dropping.
try to reboot the phone
yeah I have, I am wondering if its this phone, or the radio it uses.
Looks like I am not the only one with this issue.

Signal in and out on my g2

I got my G2 a couple days ago and I must say this phone is amazing..coming from a g1 I had for 2 years its quite an improvement. The only minor problem I'm experiencing is with the radio signal..most notably in my house..on my G1 I always had signal and internet connection. Now with the G2 I constantly loose connection all through out the house and the only way to get it back is to switch the airplane mode on and off and it picks it up right away, only to go away a few minutes later..I don't seem to have the problem anywhere else.
Was wondering if any of you guys can shed some light on if there is a way for me to figure out why the signal is so random in my house and it was ok with the G1. And why airplane mode seem to fix it for a short while.

I have the same issue, I disable/enable wifi to get reception back on...I initially had really good reception but as the days went by my reception varies a lot at my house

did u activate the sim card that came with the phone or still using the old one?
I'm still using the "old" one still but considering I got it 2 months ago I wouldn't think its a big deal unless the sim that comes with the G2 is any different?

I asked because i was told to activate the new sim card to avoid issues likes the ones u seem to be having.
I was told to replace the sim card as well. After doing so there was no change in the reception of the unit. The downside is that the sim card does fine in my Vibrant but does not work at all in My Nexus One. Tried two different new sim cards and each time the Nexus One refuses tacknowledge it while the G2 and Vibrant do. I have found no difference in signal quality or strength with the new sim. The new sim card has a much smaller gold contact area and that area is a slightly different shape,
I went ahead and activated my new sim card to see if maybe it'll fix the problem..ill let you guys know how it goes

Changing the simcards will not work. If I put my simcard in my iPhone 3G or my G1, I'll have 2 or 3 bard with 3G, but with the G2, It switches up all the time, from Edge to 3G or no data at all, with 1 or 2 bars. I also have five other family members that also have T-Mobile phones and their getting about 4-5 bars on their phones. So it's not the sim or a tower issue.
There's cleary a problem with these phones.
This mourning I woke up and found the phone with no service, no bars. I reset it and came back, this afternoon I left the phone on my bed, came back to it, and again no service, it seems the service keeps going out for no reason.
Another is, I live in a big building, when walking in and out the building, my data connection will drop, or sometimes I won't even have any service, and again the only remedy is to restart the phone to get service back, airplane mode won't even fix it.
Yea the new sim hasn't really fixed anything at all..

damn i was about to try that... guess i'll keep waiting... maybe an OTA radio update will help this cause it's really getting annoying.
I don't have a problem with my G2 dropping signal completely, but I have noticed that my 3G is very spotty. It's probably because I was spoiled the the MyTouch Slide's 3G only option.
Yes, I've noticed that the signal isn't quite as good as my G1. It's seems to be about on par, if not slightly below my friend's Vibrant.
But remember, the G1's radio really sucked once upon a time. Radio updates. They will come. Every phone that has OTA updates always gets new radio, in my experience.
I'm on my 3rd G2, mostly for manipulating the purchase price, and have noticed on this 3rd one that the spring is looser than the first two, the phone resets itself and often, and I'll loose data even though it shows I'm connected. This will happen in edge or hspda. I'm taking the phone back tomorrow.
Crappy thing I just put the ZAGG complete invisi shield on it. WIll Zagg comp me another cover you think?
If only Tmobile would activate the UMA calling over wifi. This would be the perfect phone with perfect service.
I am going to call tmobile in the morning and see if I can get any word on the UMA release. If not, the phone may have to go back.
I'm having the same problem, not at my house but at a local ihop that happens to be walking distance from where I'm moving in a week. I tried a reboot, airplane mode, even pulled the sim card and nothing worked. I got signal back once I left, but since it's right by the new place I would like to not have to deal with this.

well ive been searching around and i think ive found something that could help..
if you dial *#*#4636#*#* you will get a little screen of information about your phone, go to phone information, under phone information scroll down until you see select network type, the network should be automatically set to "WCDMA preferred" ive been playing around and i set mine to GSM/CDMA auto (PRL) and since then (about an hour roughly now) i havent lost my signal or connection in the same spot i was loosing it in my house every 10 minutes or so. not sure if this fixed anything but so far so good. definately will let you guys know if it continues to be good or if it doesnt stay consistent.
heres some information also in case you dont know which one would be best for you.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Having same issue with the signal. Swapped for a new sim but still the same. Sometimes service drops completely and I have to go through the settings menu to search for a signal in order to get some reception
Sent from my T-Mobile G2 using XDA App
phone came in wcdma preferred stock... I came by that option too but I would much rather suffer with spotty signal [HSPA] over Slow edge speeds...
that said I may turn on GSM only when I'm indoors with little coverage, should save a lot of battery.
is there a setting that forces the G2 to go for the G3 or H setting instead of the edge? I live in an area where my phone can get both and it always goes for the edge signal instead of a weak H signal and the edge is soooo slowww.

*#*#4636#*#* then phone information, then scroll down and change the drop down from auto to wcdma only. Only problem with that is if u go to an area with no 3g, u get no service and have to change it back or go under the settings and wireless to enable 2g connections

Mate 8 Internet Issue with T-Mobile

I am really sorry for post duplicated, but I have only 5 days to return this phone which I absolutely love.
However this Internet issue is really bothering me.
I just bought my Mate 8 with build number NXT-L29C636B103, but I have been experiencing mobile data issues with my T-mobile carrier that only when I get 4G symbol, I can go online. Whenever I am getting either 3G or H+, I can not connect to internet at all.
I have tried my wife's T-mobile phone, at the same location, her phone will get 4G LTE, my phone will have 4G, whenever she is getting 4G, I am getting H+ or 3G, which I can not go online anymore but on her phone, it still works.
Is is because of the version of the Mate 8 I am getting or the setting is wrong, please help!!!!
Probably wrong settings. Check your apn. And also make sure your phone isn't set up to just LTE only in the phones hidden menu
Update the software also and then check access point settings and set manually.
I check the updater, but there is no new update at all.
About the APN, I have copied exactly the same setting as my wife's S6, but still this issue.
Basically, whenever I am getting 4G above the bar, I can go online, no problem at all. But whenever it comes 3G or H+, my internet completely dropped!
I don't have that problem on T-Mobile with the NXT-AL10. I can be on one bar of HSPA and go online. There are two things possible. You have a bad phone with a bad radio or T-Mobile is doing work in your area and that's why you have no internet on anything other than 4G. T-Mobile was like that in my area two years ago until they upgraded. I would think it's the service. Try turning off VOLTE and LTE Cat 6 CA and turn on Data Roaming and see if that fixes it.

I was actually trying to help out on this issue, on another forum as well. One thing we discovered is that the settings for LTE Cat 6 CA are not on the L29 model.
Dumb question but you aren't using a metal case are you? Any aluminum case will degrade wifi and LTE to the point where it might switch over to HSPA+ due to poor LTE reception.

I have the L29 model. On T-Mobile, I was getting 3 mbps down and 1.6 mbps up. So I tweaked it around and enabled Data Roaming. Now I am getting 15 down and 9 up. Much more reasonable.
Recently had a similar issue. I copied over the apn from a tmobile device and that was the issue.
Try the 2 apn setup that should be default when you reset apn.

I have T-Mobile and it works fast but do yours say "4G" instead of LTE too?

Any updates on this issue? I'm still getting extremely slow mobile data speeds.

Does the 6P work on Straight Talk?

I have a 6P now and am trying to use it with straight talk as of last couple days. When I used the CDMA sim it seems to only get LTE when not making a call. When I try to use the internet during a call, it loses data completely and an explanation mark show up top near service bars. Now I switched over to the GSM sim and in spots where I used to get 4G with an Alcatel phone, it switches to HPSA (which creeps). Does the 6P not even have the radios for 4G? I thought it was supposed to be compatible with just about every 4G tower.
It works fine, however, with straight talk you can't use the internet while on the phone unless you use WiFi.

Starting to get annoyed with the O variant phone in the UK

It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.
try disabling WiFi calling that helped in my case
Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band
https://play.google.com/store/apps/details?id=com.ray.samsungbandselection
Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
