Mobile Data Wil Not Enable After Provider Change
I currently have a Jolla 1 and Jolla C, and this is only occurring in the Jolla 1. Both are currently at version 2.0.2.51
I recently changed mobile provider from EE to 3, in the UK. While I was waiting for my number to port over, i had my EE SIM in the Jolla 1 and the 3 SIM in the Jolla C. When the number ported, I removed the EE SIM, and moved the 3 SIM Over from the Jolla C. The next day (or day after - I hadn't needed to enable it before), I realised that the Jolla one was not showing a signal type (eg 3G, 4G, etc. - the bars are showing), and I cannot enable the mobile data - pressing the "Internet" button under mobile network highlights, but doesn't change value . At the time, it was on 2.0.2.48 and I wondered if it was the frequency issue, so I updated - but that has not solved it.
I put the SIM back in the Jolla C and the signal type does appear, and mobile internet enables with no issues.
I put the SIM back in the Jolla 1, and used the similar issues from this site to try and get it working again. I have checked the APN settings under Mobile Data and they all look correct (and are the same as in the Jolla C). I checked files under /var/lib/ofono and they look okay.
Is there some other setting or values somewhere that I can check? Or other way to debug?
