I have a Samsung Galaxy S11. When i am in certain areas in B.C. particularily Mission, BC, the house i am living in has had really poor reception. I usually have to go outside to answer or place phone calls otherwise, in the house, the calls are not hearable or just drop. I thought for the past few months, that it was just the Telus'' lack of towers in the area. However, my friend that lives here also, just bought a new phone and signed onto the Koodoo plan as i am. She gets perfect service. What is wrong with my phone?
