I remember people talking about this on the G1 forums and people were thinking this was a bug in the Android software. I do not know if anyone has provided the answer to this already, but I figured I would share what I have found. (I also posted this in the G1 section)
Turns out that tmobile and at&t have dropped their roaming agreement in several areas. The "not allowed on this network" message is due to the phone trying to connect to these towers. Even when selecting "select auto" or selecting a weak tmobile tower, because it fails connecting to the weak tower and then will try to connect to the stronger tower (att) but is not allowed.
This whole thing sucks though, because I have a metal roof that kills my tmobile signal, but I am able to get a weak att signal inside.
negatory
I believe you're wrong there about signal strength.
I've had two seperate g1's that displayed this error when inserting a TMO and/or ATT sim. The phones were both unlocked, and sitting with 2 feet of a TMO g1 with 4 bars of 3G signal.
After updating the radios to most current and calling TMO to question someone withe sense, I was upgraded through 2 levels of customer support. The last fella I talked to apparently knew things, but couldn't say much - you get the idea. He did reset my connection (or said he did) and I watched as service for all three phones on my account died (connectivity) and then gained signal again. All while on the phone with him.
Afterwards, he suggested I clear all caches, facotory reset, etc.
Low and behold, both phones worked with 3G (TMO) and EDGE (ATT) just fine afterwards. Now, was it something HE did exclusively, or a combination of his 'reset' (whatever it was) AND my factory wipe of the phones ? Got me.
I WILL BET YOU A COKE IT HAS SOMETHING TO DO WITH UPGRADING THE RADIO TO CURRENT -AND- WIPING. If i'm wrong, i'll paypal you coke money... but I think I'm right.
If a tmo person in the know, -not a speculator-, would like to grace us, that would be cool.
This has worked for a total of three "Your SIM card does not allow connection to this network" type error'd phones. All of which were unlocked, rooted, and running cyanogenmod latest.
2 cents.
I contacted Google support about this. Apparently if T-Mobile has property rights to the area where you're connecting you are only allowed to connect to T-Mobile's network no matter how poor or lack of signal there is.
Yeah, I tested this myself, tried to connect to the only tower available (an att) and was not allowed. I know you have the roaming issue is you ever see "emergency calling only" in the service bar. Means it has a signal but is not allowed to roam on that signal. I have a good signal outside and in parts of the house, just not where I am the most. There might be a bug where it gets stuck trying to connect to the wrong towers, but the source of the issue lies in the lack of access to att towers in many areas.
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.

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
Sent from my T-Mobile G2 using XDA App
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

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.

I have a Sprint Tri-Band Galaxy S4. For the past two weeks, I have had no signal in my house.
I talked Sprint into sending me a Airave 2.5+ at no cost. After I set it up, still no bars.
I tried my wife's flip phone and it got 5 bars.
When troubleshooting my Galaxy S4, I first checked "Network Mode" in Settings, it was on "Automatic".
I switched to "CMDA" and got 5 bars, but no LTE Data, only 3G.
When I tried "LTE/CMDA" I got LTE back (Not from the Airave), but no voice.
Which brings us to my question -- Why no CMDA voice in "Automatic" ??
Then just to test, I turned the Airave off, I now had 3 bars in my house from the Sprint tower.
Switching to "Automatic" left me with 0 bars again.
I would think with no signal in "Automatic" mode, it would then seek other bands and find the signal.
I can only guess that "Automatic" seeks the 1900 Mhz band, and Airave is on 800 Mhz.
I can't be absolutely sure because Sprint won't tell me.
If I'm right, why won't my Tri-Band Galaxy S4 find the signal on 800 Mhz??
Just to answer your question about your gs4 and airave it took my gs4 about 3 weeks to be fully functional with it to where it would show the correct signal and be able to send texts.

Daniel,
My S4 locked on to the Airave as soon as I put it in "CDMA" mode.
My question is: Why won't my GS4 see a CMDA signal when in "Automatic" mode?

I don't have it on automatic, I have it on CDMA in order to connect with my Airave.
My house doesn't get a strong enough voice signal, so I got the Airave.
But now I only can receive EVDO/3G data. No LTE.
I have different options than you: (I have no CMDA+LTE+EVDO mode)
LTE/CDMA receives LTE, but for some reason won't connect with the Airave.
AUTOMATIC also gets LTE, but won't connect with the Airave.
CDMA connects with the Airave. It receives EVDO from the Airave, or 3G when connecting to a Sprint tower.
AUTOMATIC should connect with the Airave with EVDO data inside my house, or a Sprint tower with LTE when near enough.
I had same thing happen while on a galaxy S 4. I decided to use my insurance and exchange the gs4 for a new one. I thought maybe mine was broken. Asurion sent me a triband Sprint Spark Galaxy S4. I was so excited to see the new speeds. Unfortunately, I still have no network connection while in Automatic mode. CDMA is the only network mode that has worked going on three weeks now. I will update when I can connect to the network on anything besides CDMA.

It was time to take the dog for a walk, so I did an experiment.
1. Before leaving the house: CDMA mode has EVDO data and 5 voice bars from the Airave.
2. Switched to AUTOMATIC and rebooted. Had LTE data with no voice bars.
3. One block from house got 3 voice bars to go with the LTE, increased to 5 bars as I went.
4. On return, lost all voice bars near my house, still had LTE.
5. Inside I switched back to CDMA, again got 5 voice bars and EVDO data.
I made 10 trips to the Sprint Store and emailed Customer Care 5 times. If they had told me I could get a signal in CDMA, I wouldn't have the Airave now. All their "Help" info said they broadcast voice on 1900 MHz CMDA and very little else.
What I now suspect is the Airave broadcasts CMDA/EVDO on 1900 MHz, Sprint also broadcasts it from their towers. Sprint is having LTE growing pains, and the signal is too weak at my house.
Unfortunately, the Spark GS4 does not seem switch from LTE to CDMA automatically, so it must be manually put in CMDA mode.
I have two towers near my home, each is about 1 mile away. I worked with microwave and radar transmitters until I retired. LTE at1900 MHz should be able to reach much more than a mile and penetrate a normal house -- unless the transmitted power is VERY low. AM radio, at 530 - 1700 MHz does it over far greated distances.
It also makes sense that my SG4 should be able to switch from LTE to CDMA while seeking, but it obviously can't.

Sorry meant LTE+CDMA, when I'm that my phone connects to airave and I can send messages and have 3g connection. But while connected to airave you cannot connect to LTE. I have LTE outside of my house, but once I connect to the airave by walking in I lose LTE and connect to 3G. So if you want LTE in your home you would have to shut off airave which means not having the stomg signal indoors. Its a tradeoff.

Let me help out on this one...
Bottom line, set it to automatic network selection, disable wi-fi "smart mode" and update your PRL (in the sydtem updates screen). Do this with the airave plugged in and connected, then do it again with the airave unplugged or away from the house. Once I did that, mine has never had an issue.
I got an airave about a year ago and took a peek "under the hood" with a spectrum analyzer. I have only ever seen the airave use the 1900 MHz PCS band, never the 800 MHz. And, yes, that means no LTE radio through the airave, only 3G.
My guess is that your device "thinks" it has a tri-band LTE signal, but the nearest tower is missing the 2.5 GHz band...
In that case, PRL update should grab the correct info.
If you are in a triband (Spark) area, then you can't do voice and data at the same time, but data is supposed to be pre-empted, not voice. One ithing to try- connect to a wifi network while on LTE and see if you can make a call.
Daniel,
I can't connect to the Airave in LTE/CDMA mode.
It may be that I have a strong LTE signal in my house. The voice signal is 1 bar or less.
Or, it may be that I have a tri-band device.
Bolo,
I tried what you wote, but it will only connect to the Airave in CDMA mode.
Both,
I guess I can live with the situation.
I have a very fast Wi-Fi signal, and I use very little data when out of the house.
I basically just check email and the weather outside.
If I want to watch a movie, I can switch back to automatic mode.
I have googled a lot on the issue, and kind of understand it's an issue with the TriBand S4 and Sprint towers.
It will lock on any LTE signal, no matter how weak.
It will only switch to CMDA if there is no signal at all, that happens in the CMDA only mode.
Sprint is promising to correct it.

To answer some of your questions:
The tri-band Galaxy S4 is tri band because it operates on three different kinds of signals: CDMA, LTE, and GSM. The latter is only used if it is unlocked for a GSM carrier (T-Mobile, AT&T, etc) or if it is being used internationally in a GSM tower. CDMA is what the voice and 3G/2G(1XRTT) operates off of, LTE is your 4G data services. Those are the two primary antennas used. If you have it set to CDMA only, it will only use voice and 3G services. If you have it set for CDMA/LTE it will use voice, 3G, and 4G (if available), but will not look for GSM towers. Automatic will look to connect to any of those, but will not connect to GSM unless unlocked to do so.
Now, as far as why it isn't working on your airave, if could be a couple things. The most likely is that it isn't compatible with your airave. It has nothing to do with the frequency the airave is using. There are several new phones that the airaves aren't yet compatible with. Assuming that's not the case, you could have a defective phone.
Another fun thing in the mix is the fact that the tri-band S4 is Sprint Spark capable, and for some reason Spark has been causing a ton of issues on phones (i.e. not calling, not texting, no data, freezing the phone up, etc), even in areas that don't have Spark up and running yet. So it's also very possible that these issues lie in the fact that the phone is Spark capable, which may persist even if you get the phone replaced.
There is a good possibility that you may be having Spark issues because right now the work around for phones experiencing issues with Spark phones is to put the network on CDMA only, which you said has given you some relief from your problems. The downside of that is that your 4G won't work with it on CDMA only.
Of course this isn't very good news, but hopefully that sheds some light on your situation.

Wiz,
I've already googled enough to figure most of this out. It seems the S4 Spark has problems switching from LTE to CDMA.
It's not a huge problem leaving it in CDMA. The Airave 3G is pretty slow, but I have a fast Wi-Fi at home. On my walk this morning, I was able to get 950 KBs on the Sprint 3G. If I need more, I can just switch to LTE.
I understand the S5 and Spark EVO are having the same issue. No doubt, Sprint and Samsung will work out a patch.

Reactivates your phone. It will reboot twice. No harm is done with this. (Unless you're using the phone overseas)

put your phone in normal mode..
settings > connections > more networks > mobile networks > network mode > cdma/lte/evdo AND:
settings > connections > more networks > mobile networks > roaming > roaming network > automatic
then, restart, then
settings> more> system update> update profile.... then restart then
go to the dailer and dial ##72786# .. this should activate the hands free activation...
then call customer care from another phone and get someone smart to do trouble shooting with you if your lte is still not working...
You will be UNABLE TO CONNECT TO THE AIRAVE unless your are in "CDMA ONLY".
Go to
settings/network connections/more networks/mobile networks
and change to CDMA .
( Do NOT select CDMA/LTE until you LEAVE the Airave vicinity)
If you are indeed connected to the Airave, you will hear a recording telling you that you are if you call *99.
You will have to re-enable the CDMA/LTE everytime you leave the vicinity of the Airave to get LTE service.
Sprint Tier II Tech informed be of the above, and I have verified it all by personally testing the above.
Now, here is the real question:
What are the EXACT DIFFERENCES between using the "Wi-Fi Calling Feature" with NO Airave - AND- using the Airave WITHOUT using W-Fi Calling.????

Do both WiFI calling and Airave deliver texts to the phone in the identical way?
On WiFi Calling, I was missing MANY texts at home. Then, when I would leave the house, all those missed texts come through to my phone, all at the same time.
Will the new Airave 2.5+ I just received from Sprint solve this problem, or is it going to be IDENTICAL to WiFi calling?
Thanks.
i am considering project Fi.
But where i live there is not tmobile signal, my friends come here with tmobile homes and they dont get signal(they live half a mile away).
Sprint coverage map says that there is "fair" signal.
so i was wondering if with project FI i dont have signal at home, the nexus 6p will switch to my wifi network and i will be able to receive and make calls?

I activated my Project Fi sim earlier in the week. T-Mobile is not strong around my house (I had to switch to an AT&T sim when I was with StraightTalk) and I'm not sure about Sprint. So far, while I'm at home, the majority of my calls are using my home wifi. I haven't had the chance to test a continuous call as I'm driving home to see if it switches to wifi, as Google indicates it will.

Yes, Project Fi uses WiFi for calls and texts when you are on WiFi.
Honestly tmobile wifi calling isn't even that great also. I am only able to get edge in my house with them and wifi calling enabled. I tried calling my phone 15 times and 2-3 times it didn't go through (it actually RINGS but my phone doesn't ring or indicate someone called, and the phone I'm using it rings and goes to voicemail) Wifi calling is at it's infancy I feel like.
I had a tmobile lte booster installed in my room for a year and it BARELY made a difference, still got 0.3-0.5 mbps speeds on their "lte"
Fast forward to last month they finally came out with a lte booster that ACTUALLY works, the previous one came was trash.
If I were you, I'd get tmobile and get the NEW lte booster, because the old one gave me 0.5 to 1mbps at it's best and the new one gives me around 7-10mbps on speedtest. Sprint has horrible signal, I would think their "Fair" signal means horrible reception.
Or just go AT&T and verizon, you get what you pay for..... they are much MUCH reliable than tmobile and sprint.

Note that T-Mobile Wi-Fi calling has nothing in common with Project Fi Wi-Fi calling, which works perfectly.
I seem to only have had one wifi call at my house with Project Fi that I've actually noticed / remembered. I have no idea why all of them don't come in / go out that way. I have a good cell signal too. But, my wifi is strong on 5 Ghz and my bandwidth is about 88 mbps down / 12 up. I only noticed that one time I got an incoming call that said something to the effect of "using wifi network name." I've confirmed the settings in the phone app are set to use wifi calling too.
WiFi calling works perfect at the house. Have very limited cell signal with every provider, so I put on Airplane mode + WiFi and zero issues?

Yeah I was just mentioning how bad tmobile is in some areas. But if you have their new lte booster, it works great. The older version barely made a difference. Came from 0.5mbps to 7-10mbps consistently
I mentioned it also cause they told me to try their wifi calling last year and it was jist decent, I still missed calls without knowing people actually called
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.
