Salloum wroteHmm. iPhone 7 never supported dual SIM from Apple. I believe this needs to dismantle the entire phone and change the connector on the board.
the picture i posted above solves the problem but i cant find it in lebanon.
new_user wrote It probably just allows you to select which sim you want to be on so you cannot receive calls on your alfa line if you were using 4g on your touch line. I think buying a 4g/ LTE router would be a better option. There is a portable version (battery powered) and a plug-in version (can be hooked to other routers, has better wifi coverage and can handle more users).
yea they will not work in parallel, and idc , all i need is to switch to the second sim when there is no 4g signal in the first one.
and the 4g/ LTE router doesnt solve the problem since it is limited to either alfa or touch signal coverage .
