Iβm currently in Belgium (Brussels, Bruges), zero reception, no data, can hook on to Proximus, but no data, very jialat. My daughter also on simba, same problem. Last week in UK, Oxford, cotswold no signal, no data. London ok. This is really bad. 1 to 2 years ago in Switzerland, also no reception no data too. I have tried everything I can, switch off, reset, manually choose operator, check 3,4,5g, even remove simcard. All No use, keep giving error message βcould not activate mobile data networkβ, anyone can help? I use simba quite a lot in Jap and Taiwan, these places ok. Sigh, simba is not reliable.
