Just tested and mine works just fine. Wondering if this is related to this bug where data connectivity drops even though it looks like the phone is still on the network? We’ve seen that same message on pings and ‘limited connectivity’.
Try 1. airplane mode 2. reset network connections via Sailfish Utilities or ofono command 3. turn off airplane mode 4. Connect to Internet 5. select your SIM
If it works, this could be the same problem, which would be good to know.
