When I'm home, or anywhere around Picture Butte I can get a maximum of 3 bars. This would be okay, but without warning it can drop to no service without using or moving the phone in any way! I've got unlimited calling, but I'm hesitant to use it due to my calls being dropped or having such poor reception people can't understand me!
Dropping from 3 to zero bars in the same spot is not normal. You should contact Telus for a network refresh. If the issue happens everywhere, than it could also be a hardware failure. Either you'd need to exchange your sim at a store, or send your phone out for repair
