SMH.

I live in Brazil, I have Tim pos in my device is oscillating much the mobile data, is always alternating between 4g and 4g + and once while it disappears the network.
I already researched the network and the phone, I already changed the simcard and it continues.

Might be normal might not be. Check the APN settings and also if possible compare another note 9 with yours with the same network.

I have 3g data, but cant make calls or texts

So I just got a HTC one from ebay (maybe not a clever idea), set it all up, put my sim in and get signal (2-3 bars) and 3G data, but if i try and send a text it fails to send and if I try and make a call it never dials out.
I've never come across this problem before, does anyone here have any ideas?
Thanks in advanced
the phone is imei barred. I see this a lot where I work. That's the problem when buying from an unknown seller, it can happen. I would go back to the seller, and get your money back if possible.

IMEI barring should only happen on that specific carrier though.

Could be unlucky and using the same network as the seller on eBay :/
OP, do you have another SIM you could try just to make sure?
IMEI barring affects the phones behaviour to accept SIM cards, at least thats what happens in the UK, which is where the OP is from

Ah right. Cos from Googling and XDA, American IMEI blocking only applies to that particular telco and any other telco it shares their blacklist with, and in my country such a thing as IMEI blocking doesn't even exist
Really?!?!?! Thats pretty mental.

Sorry, I've been out today, you all seem sure it's an IMEI bar, I'll do a check later see if that comes up with anything
I thought the IMEI bar stopped the phone from getting signal full stop, not allowing 3g data, which works, I can load Web pages.

This may sound silly, but is your sim card a data only plan, like those given for tablet contracts?

Its a normal contract that I've used for over 12 months, works fine in my Gnex
Does anyone know of a free website to check the IMEI status for UK networks? Can only find Australian ones free.
Also, is it definitely an IMEI bar if I still get signal and can use the 3g data?

Last update on this, did a check via checkmend, and you are all correct. It has been IMEI blacklisted, so it will be returned.

Glad you found that it was IMEI barred, as for the data goes, yes it will still pick that up, the amount of times I've seen it with that fruit based company is stupid. Buying from CEX and wondering why it was barred. So easy done.

How To SIM Unlock Samsung Galaxy S4

Edited..
Since lots of ppl already reported that this method doesn't work...
I just read this post in redmondpie..
and I saw the comment and one of them is trying on S4 Sprint..
II really want to try this.. but my wife brought her S4 Sprint with her so I couldn't try this at the moment..
Maybe someone would like to try this out and report this discovery?
so here's the Link:

Tried it when I read it doesn't work for us
Sent from my SPH-L720 using xda premium
Be very carefully doing this on sprint S4 it may brick it cause this process only works for ATT- T-Mobile GSM phones only
I also tried it to many times with no luck I wish this worked.

Hello. Some one try to flash radio firmware from verizon sgs4(it has unlocked gsm) ? it work for nexus but vice verca
This method DOES NOT work. Sprint BLOCKS US GSM carriers. To get an international unlock you need to call sprint and ask for one. At this time there is NO way to get US GSM signal on the sprint S4.
EDIT: Apparently this will make your phone unable to connect to a femtocell. Be careful
Do not try this mod. It will mess up your phone and how it connects to the Sprint Airave.

Please let me know how the factory reset works out for you. My phone is officially messed up. My 3g was not working at all. I would only connect LTE. After troubleshooting forever with sprint, my 3G is working again but it is very slow. I also notice that it does not auto roam to Verizon at all.

Updated: I have rebooted the phone next to the booster and then did a firmware update, PRL Update and rebooted the phone. It appears to be connecting again.

How was the speed though? It may show "3G" but my guess is that it's really 2G speed or something on TW.

I've had massive issues with my 3g after this method. The 3g is super slow and I know something is not right. Is there an app that displays the cdma band that the phone is currently operating on? I read somewhere that it screws up the phones ability to access the cdma 850 band.

What we really need to do, is find a way to undo this. Even though my phone appears to be working. I really wish I had never tried this and could go back.
Yes I hope someone figures it out. Reflashing the stock software is not enough

Update: My phone appears to be staying connected to the Airave and getting a very good signal. Data speeds were never really affected just terrible connections. :good:
I tried this also and it messed up my 3g speeds, after much searching, reading ,and experimenting,i did a SCRTN which restored modem ,lesson learned

There is another thread that is similar to this for unlocking the sim. I tried it, and possible messed my phone up. I was getting slow 3g speeds and mobile data drop outs. I fixed my issue by doing a complete factory reset/ clearing NVRAM. This is how I did it:
Dial ##786#
Choose Reset
Enter MSL
Here is the thread I mentioned just in case one of you wants to look at it. http://forum.xda-developers.com/showthread.php?t=2282683
##786# as far as I know will restore your phone to stock .
##72786# should reset your network settings. Just make sure you are in a working 3G coverage area or have a WiFi connection or it wont re-activate. This method does not put your phone back to stock...just reactivates it on the network.
Sorry for the unusable info...
But i got this news from Sprint Htc One thread, that they are able to unlocked the device by simply rooting the phone and sending a line in terminal...
Is it possible to do this with ours?
thatotherguy.. said:
1. You should be rooted
2. Download https://play.google.com/store/apps/details?id=jackpal.androidterm
3. Run Terminal Emulator
4. Type "su" (excluding quotation marks) and grant it superuser permission
5. Type "am start com.redbend.vdmc/com.htc.omadm.test.TestMainActivity" (excluding quotation marks)
6. You will get menu on your HTC
7. In that menu, select "API", then scroll down 'till almost end and select "simlock"
8. Reboot the phone and hopefully it would accept GSM SIM
9. Enter *#*#4636#*#* in your dialer
10.In the phone information section(the first one) set preferred network type to something that is GSM specific: "WCDMA Preferred", for example. The phone will switch to GSM mode

3G just dropped and hasn't returned??

I've been on Viper rom for the past several months. Today my 3g just dropped and it will not turn back on no matter what I do. Airplane, reboot..nothing. Anyone had this issue? Could it be a PRL issue?
It's most likely not a PRL issue. Try updating your data profile, but more then likely it's a Sprint issue and nothing to do with your phone. My 3g has gotten so bad I don't even try to use it anymore. If I can't connect to WiFi, I just shut data off completely. Sad that Sprint has come to that.

Nah I doubt it. My G/f has Sprint, her phone is fine. A couple buddies at work have Sprint and they're fine. It's been like like the last 10-12 hours at work, they use their phones just fine while my data is 100% gone.
I'm on wifi now, I did a profile update and nothing. This is crazy...it's almost like I have mobile data switched off but it isn't. Never had this issue before.

Check your SIM card. If your towers have been upgraded to NV, 3G AND 4G data won't work if there is a problem with the SIM card. People have said the SIM only affects 4G data, but this is not true if the SIM card is removed or not detected in an NV area. Usually the phone will tell you if there is a problem with the SIM card though.
I just went through this on my new Red HTC One because the SIM Wirefly sent with the device was defective. I noticed I could only get 3G from my Airrave, and not any towers around here. That is because the towers here are NV towers and it is connecting in CDMA eHRPD mode for 3G/4G handoff, which requires a SIM card to work properly. I flipped the phone to CDMA only and it is working fine now in EVDO Rev A mode.

3g on. Verizon

Do I have to keep my connection on global if I get to an area that my LTE drops off to get 3g? I had it set to LTE but got the roaming so I put it on global got 3g then got LTE when I got service back. Is this the normal process? I just got nexus 6 and wasn't sure if this is normal. Running cm12

Set it to Global if your outside of US territory LTE (Recommended) if you're within the US. Always remember to enable Airplane mode or Reboot when making the changes as a precaution.
Sent from my Nexus 6 using Tapatalk
Global and LTE are exactly the same if you are using a Verizon sim card. Global just allows you to use a GSM sim (typically for overseas travel).
Ok so I noticed if it drops I don't get 3g so is their a way to get 3g. My situation is when I put my phone in my locker it loses 4g and would default to 3g now I just get a ! On the network signal. So did I lose ability to get on 3g. I think I read on here that can happen
Yes surely lost 3g cause if I switch to 3g it gives me the !. So how do I restore 3g

I had same thing. Turned on Allow Roaming Data, and it goes into 3g. I'm assuming that since I'm in my home area, this won't cause me incur roaming charges.
Anyone figure out a solution for this yet?

Mine will get 3g just have roaming enabled. With the way big red is kinda makes me nervous. Do you need roaming enabled to get 3g?
My roaming is off and mine will go between 3G and LTE with no problems. It does that a couple times a day at my work.
I found that on stock ROM it switched 4g to 3g fine. On aosp Roms I need to have roaming data enabled to get 3g and it says I'm on network 0000000.
I remember santod040 fixing that issue on HTC one m8 or was it digitalhigh I don't remember.

Can you people who are claiming that phone switches to 3g confirm that you are on Verizon? I was not aware that that this phone works on Verizon 3g since it is CDMA technology.

Yes am on vzw can get 3g without enabling roaming on stock rom, on custom roms at least the ones I've tried roaming needs to be enabled to have phone switch between 4g and 3g. N6 has only two variants us and the rest of the world. The us version has a cdma radio don't know about the other. Also on verizon there is no voice and data at the same time... yet may have it in the future.

Xiaomi Mi5 GSM issues. (Resolved)

Resolved: Wouldn't connect to T-Mobile networks, connected fine to AT&T. Guessing it was band limitations. (Should have checked bands.)
Here in California, USA and can't seem to even connect to the 2G/3G services on T-Mobiles networks. Popped in my SIM card last night and got a MetroPCS banner for about a second. Haven't been able to get it to work since. Always no bars, no service. Any tips?
Here's a screenshot of my lack of signal. I seem to get signal for a second, then it just disconnects. Any help is appreciated. Thanks.
I bought new xiaomi m5 and straight away got problem with the touchscreen. If anybody had similar problem, will go to the shop to see what they say anyway.

I always get emergency calls only, it reads that there is a SIM card inserted for both slot 1 & 2 plus it reads the phone number of the card AND even contacts on the card but doesn't connect to the network. :/
is that some Quality Assurance issues or a general problem?
Also getting issues with signal, weaker than any other of phones , sometimes drops call, or caller hear me with pause, ( i'm techinician, repairing phones, having a lot of tests), i'm in EU. Because lack of band 20 4g+ isn't working here i think. Overall a lot of people got defective units. Mine also have loudspeaker problems, tryed to calibrate via service menu, still the same.

Please let us know how it's working on AT&T. I'm on AT&T and am very interested in this phone.
just as a 2nd review....I am in NJ on ATT and works very well.
although, it's a pain to debloat everything everytime I tinker with settings or try to unlock!
