Only when the phone is set that XOX becomes the default Internet choice (dual sim phone), I was able to see the APN settings. They were "celcom3g" and some other things, deleted that and set new APN name and value to 'XOX'. Then I Force LTE only, LTE can connect. But when I brought XOX back to not the default Internet choice line, Force LTE will result in no line even though the other SIM card is put on UMTS as this phone only allows 1 simcard on 4g at one time (It only locks to GSM now because I presume Digi shut down their 3g).
Actually I'm not quite clear about the 4g and 2g being simultaneously needed for XOX. Andrea2k, do you mean that when you choose LTE/GSM mode, both these 4g and 2g will be ON just for that XOX line? One for internet and one for sms/calls? It seems a little strange for me as I always assume one SIM only locks to one band / G at one time.
What phone were you using again? Like I said, some china phone has certain band disabled.
Whether or not you set to LTE only, it will still connect provided your phone support the band the telco is using. When you set your phone to LTE only, due to no volte, your phone would not ring since it cant switch to 2G to receive the call. It still ring like normal for the caller. This I already tested since customers called me via office number to screw me after I didnt pick up calls for 3days.
Just look at this screenshot. My yoodo is a spare number I bought because nice number. Never activated data, just call package every 60days grace. Right now already inactive but still connect to 4G. Cant show with my xox since I had activated data recently to game on my 2nd phone.
Update:
One of my xox used in tablet also connecting to 4G without subscribing to data currently. I only on data sometimes when needed.
