Hallo,
I have a world-wide gsm version of the htc Hermes. The device is simlock-free and always has been. I put the official, albeit leaked, WM6 rom on it and it works great. But: last week I switched providers (for better data plans) and here is the result:
Data connection works just fine
SMS works just fine
But, I can hardly make calls and I don't receive any. The problem is not the network, because I switched phones (I put my SIM in a €26 SamSung phone which I use when I go camping) and I receive all of the calls. When someone calls me, they hear silence for about 30 seconds and then end up with my voicemail.
Any ideas as how to solve this? Both my old and new carrier are GSM. The only difference between them is that my old carrier (Belgium, Proximus) uses has a 3G/HSPDA network whereas my new carrier (Belgium, MObile Vikings; uses the network of BASE) has an EDGE network. Both operate on Dual Band.
EDIT: Would a radio upgrade do any good? If so, any suggestion for a radio version?
Thank you!
Come on, 80 views and no reply. Someone must have had an idea!
I did a radio upgrade (1.48-> 1.50) but that didn't solve the problem. Any other ideas?
I have TyTN and similar problem. Installed WM6, and worked fine for a 6 months. Few days ago problem (Strange?) started. I have GSM signal, I can make calls, I can receive calls from fixed lines and other GSM operators, but I can't receive calls from users of my domestic network?!? They get info Connection error? Please, HELP.
Also, when I ask request service for Call Barring I get info "Can't read specified service..."
Change the Sim
Long shot but have either of you thought to get a new sim from your current provider (port your number across if necessary) and see if that works?

I've changed SIM card, it's still same problem! But, with a SIM card of other mobile operators I have no problem.

Sounds like a problem that's related to the network provider you are using. Have you chased down their technical dept for help? All else fails, move providers.
Once had a problem where I could not get mobile signals at home but could everywhere else. Turned out my service provider had issues with broadcasts to the cell near me.
They fixed it and gave me my charges back equal to the time the system had been out.
Good luck with it.

Hello,
I recently upgraded my Huawei Nexus 6P to 6.0.1 (dirty-flash, sideloaded).
I had trouble getting LTE to work at first (turning on/off Airplane Mode makes LTE work). I kept trying to change Field Test settings to make LTE work.
However, when I factory reset it the phone won't make or receive phone calls.
It sticks on "dialing..." and it just won't work. However, data and messaging work just fine.
I forgot to back up my EFS partition so it's partially my fault.
My IMEI number and MEID show correctly, however on the My Verizon website it shows a different MEID that's nothing close to the original one. The last 2 digits were different. Neither the MEID or IMEI were changed during the upgrade process, so it should have worked fine.
I recently called Verizon Tech Support about this and they said they'd change the MEID within 72 hours to 4 days. (I called Friday evening)
They kept having issues with the server rejecting the MEID and I checked, it's not blacklisted. They told me about a "wrong form" being filled out and ran some tests and nothing worked.
The phone MEID and Field Test menus showed properly though, just calling any other number (even Verizon's activation number) won't work.
I kept factory resetting, even downgraded to 6.0 (clean flash with recovery/radios, unrooting and all that), and LTE worked better, but STILL no phone calls!
Whenever I try to activate it on the website, it keeps telling me to contact their number. I'm not sure if I'll need a new SIM card because I've tried another SIM card and will also not make calls.
I'm not sure if calling has to do with the MEID or IMEI or anything else.
Do you have any tips/suggestions to fix this annoying issue?
Thank you,
Exec360
I've seen the issue going from Wireless to LTE and vice versa but I have no issue making or receiving calls. Texting and MMS work ok also. I went from 6.0 to 6.1 by doing a factory image flash. Now I'm Chroma and I'm curious if I would have this same issue on Stock so I will probably flash factory or a slim rom stock tonight. I'm on Verizon and had a nexus 6, I popped the sim in my 6p and it activated with no issue.

Same here, except I popped out the SIM from my iPhone 5S.
Ironically, when I put the same SIM back into the 5S, calling and voicemail, in addition to data worked, even though the device was recently deactivated from Verizon.
I'd say the issue probably comes up from a corrupted IMEI/MEID or other identifier. (Not completely sure about this though — the IMEI/MEID was the same between popping in the SIM for the first time and after resetting...)
Verizon detected my device as a Huawei 1511 phone and thinks it's an old Samsung feature phone when I run it through support/help pages.
I have the exact same problem with my phone and I don't know what to do.
update: I just flashed the efs backup file and it worked again.
I forgot to back up my EFS partition and I had 2 chances to do so...
My IMEI, MEID and SIM ID show perfectly in the About section, even when factory reset and bootloader locked, but calls still don't work, very odd.
I used Wugfresh and just about every IMEI recovery tool I could find (EFS Professional) but it keeps giving me errors such as "Access Denied..." with BusyBox installed.
Still no email or response from Verizon techs tonight, expecting one tomorrow.
If not, I'll have to RMA.
More specifically, I cannot find an EFS folder or a nv_data.bin file in any file explorer — Root Explorer, Solid Explorer, TWRP, etc.
Alright, I've actually figured out that the problem is NOT the EFS after I sent it in to Verizon.
My IMEI and MEID number and everything else were actually just fine.
It wasn't flashing or anything that ruined my phone... I recently called Verizon one night on my phone about LTE issues on 6.0.1 and after that, the calls just stopped.
In fact, the problem IS on their end.
They gave me a new SIM card and it didn't work. They realized the phone was new on the network and that would cause incompatibility issues.
Now I have to ship my phone to their IT department which takes about 2 weeks.
If that is your case:
Verizon guide to getting your calling back:
First, I'd try flashing an old EFS backup when your phone was working. If that doesn't work, call their support number (1-800-922-0204) and select the tech support option or say it if it asks.
Give them your SIM card number to try activating the phone. If that doesn't work, you can still send in your phone — just ask them and a phone kit will ship.
Sending it in to the IT department will take around 1-2 weeks, so you should definitely have a backup phone or communication device on hand (you can also just use Google Voice from a PC which is a great temporary solution).
I'll say, BIG props to Verizon for giving us very good support.

AN easier method is to use any Verizon phone with a microSIM and activate on their network.
Once the SIM is active, cut it down to a nanoSIM and put it into the Nexus 6P.
It just works. All this about sending your new phone to them for two weeks is crazy.
I pulled the SIM from my LG G3 and cut it. Up and running in minutes.

Unfortunately, my other phone does not have a microSIM. NanoSIMs usually work with LTE connections.
Trimming a microSIM is dangerous and could actually damage your SIM card tray and your phone.
Thank you for the advice, but I should warn you taking that risk may actually damage or cause issues with the SIM card itself such as not being able to read its SIM card number.
EDIT:
After 5 days, 3 factory resets, and many flashes of the older radio, it has been SOLVED!!!!!
First, try disabling, reinstalling the factory version of Google Connectivity Services, then updating it in the Google Play Store.
Next, dial *#*#4636#*#* on your phone application to get to field test mode. This function will work no matter whether the phone is working or not — it's just an information screen.
Click the 3 dots and select "change radio band". Select Radio Band 6, NOT USA or Radio Band 7 — Verizon told me to try both of those and they are glitchy.
Source: "Attaching 2 screenshots. One with band 6 where calling works but data is 1x. Another with USA band where LTE data works but no calling. Looking closely it's set to emergency calls only." (http://forum.xda-developers.com/showpost.php?p=64149076&postcount=8)
Now my GSM service is working and calls work extremely well!
Glad it had nothing to do with EFS/IMEI numbers after all.
Make sure to set your APN to "VZWINTERNET" if it hasn't been set already.
I'm glad I can share this with XDADevelopers so that they can benefit from this information.

In the US, all carriers are supported for Nexus 6P use. Since you live in Qatar, you may have a different carrier.
Here are a few other points or solutions for this issue:
If your carrier is not Verizon, does your carrier whitelist the Nexus 6P or only phones sold through them?
Do you get an IMEI number in the Settings application? (don't put it here for privacy reasons) If you don't, then your issue most likely has to do with accidentally deleting or modifying the EFS partition. Try restoring an EFS backup. ALWAYS back up your EFS before you install something else or root your phone — and keep it in a safe location! Alas, that was not the case for me.
Have you tried turning Roaming on inside your cellular network settings or have a specific roaming plan?
Do you get decent reception when making calls in Qatar? Where do you have this issue most, indoors or outdoors? You should get 1x at least.
Try the field test mode (*#*#4636#*#*) in the phone application. Go to "phone info".
If you see "GSM service: emergency calls only" on Verizon, the GSM band is not connected which makes phone calls. Switch to Band 6.
Otherwise, if you see the same thing for GPRS, try switching to another band. I'm not familiar with carriers except Verizon or other US carriers (AT&T, T-mobile, etc.)
I've emphasized this a lot, but try a factory reset. Lock the bootloader and remove your custom mods to the system. It may just work for you.
The case may be that the phone service does not work in Qatar, your reception is weak, or you have a specific phone plan. It may be your carrier not being compatible with certain bands, like GSM.
If that is the case, try calling their support and ask them for any possible solutions to the problem.
EDIT:
You also stated that you bought your 6P from Ebay. Many risks can come from buying used phones off of there rather than the official websites. It's likely that someone messed with the EFS and IMEI numbers.
It could be a stolen phone too... in those cases, it would be illegal (in some countries, not sure if in Qatar) to change the IMEI number unless you have an EFS backup. Sorry, you may just be out of luck. Try another solution like Google Voice or Skype (paid) for now until you get it fixed.
Thx bro

Here in qatar, i have one friend having the same fone from amazon and it is working fine. Here no CDMA plus texting and data are working. If the efs is corrupt or as u say screwed, it would work data and text? Band USA and 6 re ok with data and text.. Band 7 dead.
In general, it may corrupt the phone function but texts/data may work fine.
Most carrier connectivity issues usually come up from a corrupt EFS or the service not being activated on your plan.
http://forums.androidcentral.com/ask-question/423732-understanding-cwm-backups-efs-partition-etc.html
For you, it seems like Band 6 is the correct one. No CDMA — and GSM is working again. Good job
Another method to try:
Update the Preferred Roaming List (PRL) - dial *228 on the phone app or figure out your carrier's PRL update number
That might work, didn't affect my calls since I don't use roaming services.
By "Band 7 dead", do you mean that the service just won't connect? My issue came from messing with the bands to fix the LTE issue and messing up my phone.
Try to call your carrier's support — try getting a new SIM card or collect information about the Nexus 6P compatibility, if they don't have it on their website.
Was the phone working since you first used it? Have you rooted or done any system-level modifications to it? Also is your carrier Verizon, because I don't think they have strong roaming service in Qatar... I am in the USA right now using Band 6, working fine.
https://community.verizonwireless.com/thread/494218
When you dial, do you get "Dialing..." and just have to wait until it hangs up, or is there static, or a carrier message? Does your friend have the same carrier (Verizon) as you do?
Sorry I'm asking so many questions. I just can't quite identify your issue very well.

Thanks for exerting all kind of possible solutions . really appreciated ... I ll explain next everything ..
First of all I'm no verizon subscriber .. I just got the phone from ebay shipped to qatar .. that's all international buyer ..
well secondly, the service is activated. here is different than yours in activation process. Plus my sim card is working on all other devices, opo, op2, opx, mi redmi n2, moto g ...
I believe the problem remains in the piece I have now (nexus 6p) because im used to buy phones from the US and they work fine expect some missing LTE bands that does not really interfere with calling service.
If the EFS/IMEI is corrupt, will it register on the network normally? will data and text still work?
Band 7 dead means no text no data and surely no calls ... plus when I chose it, i always get called ended right after i press Dial a number
experience with other bands:
band USA: text and data working fine ... calls: when dialing, it keeps dialing until the network fails and returns again like reconnect (the bars disappear and return again) and when i hang up, it respond quickly and execute the action but on,
Band 6: text ok data ok , calls no .. but when dialing, it keeps dialing normally till it gives me (call ended ) and if I try to hang up after few seconds, it freezes the phone for like 10 seconds till it execute the action of hanging up ...
so the USA band is the most responsive band in terms of hanging up ..
when I dial *#4636 .... , and access phone information to change preferred network, it is usually set to LTE/CDMA/GSM (PRL) >> if i try to change it to LTE/GSM (PRL) because no CDMA here, it usually return to the default after restarting the phone .. it does not really change the network if, for example, I choose GSM only .. I still see LTE on the bar .. moreover, when i try to choose 2g from cellular networks from settings, it does not reflect and I still get LTE working .. weird ..
** in all cases, FYI, I always see the carrier name in the top left corner of the screen.
*228 does not work as Im not verizon .. plus any USSDs are not going through as it gives error "connection problem or invalid MMI code"
when I try to access caller ID, it gives error " network or SIM card error".
I tried to call the carrier but they could not do anything. I'm still expecting a call from their back office team who ( i assume ) has more experience
getting a new sim would not help because I have tried different active sims different numbers and I also tried the second carrier here in Qatar (vodafone) and the problem persist.
the fone never worked since i reached Qatar. It was not rooted. I only unlocked BL and flashed the first factory stock rom (fully including the radio), yet nothing
wait wait please don't lose hope
one friend here is also giving me ideas and solutions to get over my isssue, he suggested i flash chroma rom bcz it has more bands. I will flash it and give a feedback.
I really appreciate your efforts and also his efforts @Soulfly3
pardon me if I wrote too many things and for giving all my trials not in order
Thanks
Thanks everyone for helping me resolve my issue. biggest thanks goes to @@scoobysnack who helped me greatly to get over it.
Installing Chroma ROM solved the issue because basically it was a problem of bands. Chroma had more bands that work in Qatar. and I could return back to stock rom again without any problems ( but don't mess up with bands in phone information )
Thanks @Exec360 for offering me your great support >>>
I told you chroma would solve your problems. it has different bands to select and I figured the "AUS" bands would work.
Any advice for those of us operating on Verizon's extended network? I'm using my device on the Appalachian wireless network (with whom Verizon has a network sharing agreement as part of it's LTE in Rural America program), and I'm constantly getting the roaming indicator, even though I know I'm not roaming. I've never dealt with this on any other device, and I've used 4 different devices encompassing both Windows Phone and Android. If I switch the CDMA roaming indicator to "Home", the roaming indicator disappears and the usual LTE indicator appears, but I'm unable to make voice calls. If I switch the roaming indicator to "Automatic", I can make voice calls but the roaming indicator returns and the device tells me I'm roaming inside the test menu, even though Verizon tells me I'm not incurring roaming charges. If that's true, then the roaming indicator is just an annoyance, but it's there constantly (even when on WiFi) and for me it's a significant annoyance. Is there anything I can do, or is this just something I'm going to have to live with?
I purchased a brand new 950XL Single Sim to still use on Puretalk an ATT carrier. Strange it only drops call and will not call out? I have a prototype 950XL ss that makes calls with the same sim. The prototype is stuck on a really old version of Windows Phone.
The new phone I purchased took the entire day to update to the latest release and refuses to make a call. Texting works fine.
Any ideas?

First, ask the mobile operator of your SIM card.
Ok, I tested everything with my carrier. The new 950XL can text and surf but it will not call out. It says drop call immediately.
Any help is appreciated!
Does it drop toll free emergency number without SIM and with SIM in phone?
Did I understand correctly that it receives incoming calls?
It drops all calls. As soon as you hit the call icon it drops the call without trying. Incoming calls do not work either, they go right to voicemail. My other 950XL SS that is a ATT prototype and stuck on an early windows version calls out just fine.
It is possible that the Radio Interface Layer is partially corrupted (software, by an incorrect update or hardware).
Switch to GSM or HSPA and try.
I don't see where to do that in settings?
I tried this and it didn't fix the problem. Maybe something is corrupted? I did notice that I don't have the double tab to open screen option.
Thank you.
It seems to be because the international versions of the 950 XL do not support VoLTE.
Do you have a suggestion what firmware I should flash for success?
Just started trying to get this phone working. Does anyone have a success story with the 950xl single sim on a US based carrier?
I have that phone in Spain and I can't call too. I just rescue it and I would love to make it run.
