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.

I bought unlocked, sim free HD2 inserted the sim of my usual Mobilink network the phone wizards automatically configured the setttings but to my strange I cannot dial or receive phone calls, I am receiving and sending sms perfectly the phone GPRS working alright tried different methods of changing band but nothing is working to dial or receive voice call. In order to check if there is problem itself with the phone I tried different network (Ufone) sim and the phone is working perfectly without any problem so I am stuck that I cannot use my network which I normally use and I dont want to switch network, if somebody can help to fix this problem.
I have a stock Moto G4+ xt1641 from TELUS (Canada) and it refuses to connect to any cellular network (LTE, WCDMA or GSM).
It's not blacklisted by the carrier.
It was working fine last night and all of a sudden as I was on a call, the call disconnected and went "No Service" / "Emergency Calls Only".
I power cycled and I even a factory reset.
I tried a FIDO (Rogers) LTE SIM and it appears INTERMITTENTLY to register on the network, but refuses to make/receive calls, SMS or data. At this moment, it has gone back to no service.
Clearly it's some sort or radio issue. Any suggestions to try to fix it?

hello this is my first post
i unlock the moto e4 verizon with unlock code and it was unlocked but the phone cant make calls anyone else have this problem with the moto e4 verizon
What network u trying to use ? GSM services will only work for data and text .calls just end
Why don't you flash the stock images from the unlocked variant?
Be default, Verizon lock prepay phones from making call.
Although that's interesting because call works for me using Mint Sim. Try factory resetting as well.
Had the same problem, and then noticed that there was no APN listed. After manually entering the APN info from my other T-Mobile phone, I was able to make and receive calls without any trouble. Only thing was that the network drops to 3G during the call--not sure what to do about that.
maybe worth a shot
change preferred network from 4g to 3g, make a call, and change preferred network back to 4g. It's been working for me in cricket that way. same thing in post #8 of this thread

got the code from ebay
The Verizon E4 Plus works fine for me after unlocked. Tested with both AT&T and Tmobile with no issues. I purchased yesterday at Target for $99 and requested $2 unlock code yesterday. Got code this morning and it works great.
For some reason the device automatically drops to 3G when making or receiving calls. However voice quality is good if not HD.
Overall this is a pretty strong device for under $100...shame is you cant unlock bootloader.
Here's a video showing receiving call and dropping to 3G.
After putting my Cricket sim card in, entering unlock code, and setting up the phone, I followed the "trick" so phone calls would stop dropping to 3G and stay on 4G LTE but it would not work. I tried the following:
1. Change to 3G, made a call, change to LTE, made a call and it still dropped/showed 3G
2. Change to 3G, made a call, and restarted phone. Change to LTE, made a call and it showed 3G still
3. Change to 3G, made a call, and restarted phone. Change to LTE, restarted phone, made a call and it showed 3G still.
The Cricket APN is set correctly as I see 4G LTE when not in a phone call. I am able to make/receive calls, sms, mms (for mms had to use Textra over the default Message+ app).
Any other ideas I can try to get phone calls to be on LTE?

Hmm...someone on Slickdeals replied to me saying for Cricket, to get "HD-Voice", you need compatible Cricket phones, which the Moto E4 Plus clearly isn't --> https://www.cricketwireless.com/support/apps-and-services/hd-voice/customer/compatible-phones.html
Not a big deal about having phone calls drop to 3G. I was just curious because people and the wiki mention to do that "phone 3G/LTE" workaround.
I can't add any APN. On the Settings, I get a message "Access Point Name settings are not available for this user". There is no way for me to add any APN. Mobile Data works on my T-Mobile SIM.
Edit: Never mind. My bad. I was juggling two of these phones and only one of them had a SIM card. The one with the SIM card allowed me to add an APN.
But I wonder now how this is going to work when I travel abroad and have to use a SIM that would roam across multiple networks. I'd have to add each one manually? Without knowing which networks are available?
Phone(verizon e4plus ) took an ota while on att sim (was sleeping didn't notice til now ) now I only get busy signal tone when I call out I still have not and text messages just can't call out again without that dial tone happening
I've got a very weird issue with my Galaxy S8 (SM-G950FD)
After working fine for about 1.5 years on the network it suddenly wasn't able to make and receive calls anymore on the Lebara (Vodafone) network in Australia.
The issue spontaneously disappeared a few hours after it first surfaced but reappeared and has not gone away since.
Internet and Txt/MMS are working normally. But when someone calls me it goes straight to voicemail and when I call nothing happens for a minute or so and then it "disconnects" but no tone
When I go into the phone app and try to retrieve settings like caller ID and/or forwarding it gives the following error:
Failed to read data
Something went wrong. Check your
Sim Card or network connection,
then try again
When I insert the sim into an S7 it's working. When I insert the sim from the S7 into the S8 (Optus network) the S8 works as well.
I've performed a factory reset (without restoring the settings)
I've gotten a new sim and Lebara has ported the number to it but that didn't help
Being a dual sim I've tried using the shared sd/sim slot but same issue.. data/mms/txt working no voice.
I've tried copying the apn settings the S7 displays with the Lebara sim to the S8 but that didn't help either.
I've now used Odin to flash the phone back to the Oreo version with the December 2018 security update and that didn't help either.
Any other ideas?
Thanks
I've managed to narrow down the issue a bit.
Also went out to purchase a Vodafone Pre-paid sim. That one didn't work either at first but after some troubleshooting with support of Vodafone we've found out that the S8 doesn't connect to the 3G network of Vodafone Australia.
When I have the SIM of another provider in there and limited the network mode to 2G/3G autoconnect the phone just finds the 2 other networks on 3G (AFAIK 2G has been phased out).
I've tried to get into the advanced service mode but this doesn't seem to be possible anymore.
Is there a way to try to see which bands are active on the S8 and better yet enable them all?
