LTE, UBports OTA-15 and Vollaphone
-
Maybe there is a problem with the APN in the settings.

@kristatos
Thanks to all for your tips.
My carrier is Deutsche Telekom (Germany). With an Android mobile all works pretty well. It's a nano SIM (about 1 year old, should meet the requirements, up to 300 MBit/s are supported).
And yes, I tested it in several locations with very good reception conditions. No success.
If 3G works, 4G not, are there any special/expert APN settings affecting 4G? Maybe to be configured via CLI? -
@ubtouch-newbie
Is vollaphone with androïd works in 4g with same sim? -
@ubtouch-newbie Weird issue. Apn settings are the same on 3G and 4G. Are you on OTA-15 Stable? Also try to reinstall UT with UBports installer without Wipe nor Bootstrap.

@stanwood
Yes, I'm on stable. Good idea! I'll try this the next days and report.@Keneda
Unfortunately I just have no Vollaphone with Android to test it.Thanks a million

Volla OS and Sailfish OS must probably work like a charm, at least it does for me, but cellular data are non-existent with UT on my Volla.
SIM, cellular data and APN management are not yet mature on the Volla FOR UT, even if UT can work CORRECTLY for some : it's the lottery unfortunately !
I can well imagine the puzzle for the Volla's developers at the moment !

For those in the USA - my experience so far (in central Texas) has been that with T-mobile you can make and receive clear phone calls and text well, but that mobile data has been limited to 2G (most likely because of frequency band incompatibilities). I tried out a SIM at my local AT&T store and got fast 4G/LTE immediately, but was unable to make a phone call. I have a feeling the only current solution for a fully functioning phone able to do both calls and LTE mobile data would be to flash Volla OS and change my carrier to AT&T.

@ubtouch-newbie Can't you install Volla OS to test?
-
@ubtouch-newbie I have also a Vollaphone to test and can say no Problem with congstar apn. It works perfect! I didn't change the APN.
-
@fp2andfp3-user
Thanks a lot!
Do you use UT with an Congstar LTE plan or just 3G?@Keneda
I think I could, give me a free day to focus on that
-
@ubtouch-newbie I have lte congstar and ubuntu touch
-
@ubtouch-newbie can you please try to run
/usr/share/ofono/scripts/set-context-property 0 Protocol ipin a terminal and tell us if it fixes the problem? -
@fla
I got the error message
Error setting context /ril_0/context1 property Protocol: org.ofono.Error.InUse: The resource is currently in use"L" is shown in the status bar, so the context should refer to lte?

@Fla
Addendum: I just checked the interfaces and got:
ccmni1 Link encap:Point-to-Point Protocol
inet addr:10.24.58.241 Mask:255.255.255.0rndis0 Link encap:Ethernet HWaddr a6:72:65:18:f2:93
inet addr:10.15.19.82 Bcast:10.15.19.255 Mask:255.255.255.0However, pinging an official IP-address doesn't succeed, probably the above IP-address (ccmni1) is not assigned by the provider.

@ubtouch-newbie I also use the vollaphone with OTA-15 and congstar (D1/Telekom). My sim is ~5 years old. When I stated with the vollaphone I had to type in the APN-settings manually. Since I did that, it works fine and I can use LTE.
Yes, the "L" in the indicator bar stands for LTE.

Hi all,
The issue is solved. After poking around and trying different things without success (including the attempt of a reinstallation with the ubports installer - no device found or several communication errors) I just did a full reset of the device as a last option.
Success! Unfortunately I had to wait until I had the opportunity to test the LTE function in an area with good LTE coverage - therefore the delay.
But now everything is fine. The phone connects automatically to the network, no manual input of APN data is necessary.
Sometimes solutions are too close to see them.
The root cause of the problem, however, remains unknown.
Thanks again for your support and tips

Hi @ubtouch-newbie , I'm also currently in the process of setting up a Volla phone under ubports. Just for clarity, can you describe the exact method by which you factory-reset your phone? Did you just do System Settings -> Reset or something more advanced? Asking just in case I encounter a similar problem. I've only verified working phone-calls and the wifi so far.
