Boarded flight and Captain prior to door closure said they were having issues because of 5G networking; asked all passengers to turn their phones to airplane mode and WI Fi. We pushed back from gate; more PA from Captain made with same issue FA (Flight Attendant) walked through cabin to ask passengers to turn their phones to airplane mode; but had no way of enforcing this and from my seat I saw 2 passengers scrolling through their facebook accounts and  watching facebook videos. Captain final came on PA and said we would have to return to the gate and deplane and have Maintenance take a look at aircraft systems; which is what we did we were told that we did not have contracted Maintenance at ZZZ for this aircraft and we took approximately 2 1/2 delay before we were on our way again. Wanted this event to be brought forward and I believe we will see more issues concerning the 5G and passengers putting their phones on Airplane mode.
Flight Attendant reported possible 5G interference with the aircraft and passengers not setting phones into aircraft mode as instructed.
