I cannot use my cell phone inside my house
check for interference from household appliances
check the material used in the house cladding as it may be blocking the signal
indicates an environment problem in the house as different phone makes are in use and the only common factor is the service provider
you may have to pay to get a technician in to the house to measure the signal strength from the cell tower inside your house
if you have any electronic vermin plug in units in the house try switching them off as they work at a frequency that may be affecting the performance inside the house
