On my side the only I encountered such a issue is when I switched carriers and I use prepaid system. Carriers here prepaid automatic systmem subscription and once off. Using once off gives 30 days use and will until you re-subcribe to bis after said period while auto will reactivate BIs aslong there is neccessary money available on the sim.
If for some reason after having chosen auto and if the network had issues downline the and you tried activate 30 days once off , like I had done had me disconnected for 5 days before issue resolved after phoning my carrier. Before contacting my carrier registering via host routing table and battery pulls did nothing.
Forgive my grammar back there I had a phone call in the middle of the post and lost my trail of thought and I cannot see edit button because I'm obviously posting from my phone. Full desktop mode is not mobile friendly.
