There could be a number of reasons why you have recently lost signal on your cell phone when in your house. It could mean there is a problem with your handset and that it needs repairing; or it may be due to a fault with your local mobile transmitter.
A method which sometimes works when a phone completely loses signal and network is to turn off the handset and remove the battery. By replacing the battery and turning it back on after a few seconds, you may find this solves the problem. This is because sometimes when a phone has been on for hours or days at a time it can cause a minor error. Turning off and back on often resets this error, and restores the phone to full working order.
If you have tried the above and are still not receiving any signal, then you should check with family and friends who use the same service provider. Have their signals dropped recently? Do their phones work in your house? If the answer to the second question is no, it would suggest there must be a problem with the local transmitter. The only solution here is to wait until the transmitter has been repaired before the signal will return to your phone.
However, if other people's phones are picking up a signal from your house, it could be worth taking your phone to a repair shop or to the store you originally bought it from. They will inspect the phone and hopefully locate the problem. If they can't help, it is perhaps worth contacting your network. Otherwise, unfortunately, it looks like you may have to purchase a new cell phone.
We have been experiencing the same problem. We have a bad tower in our area and the next nearest is blocked by too many trees. Call your cell provider and tell then your reception has diminished and they will order a repair team to look into the tower for problems. Also.. Make sure you power down your phone for a few minutes every day, that resets the connections. Sometimes when reception isn't good you can power it down for 2 or 3 minutes and it will be better.
Are there any new structures in your area? This could be a reason for it to be doing this. Call your provider and have them come out and see what the reason might be. Hope this helps, good luck to you.
I live in Arizona and I have horrible cell coverage in my house. I have had Verizon Wireless since 2001 and never had any issues. So I asked around and here's what I found out. My house was built be Centex Homes and their homes are Energy-Star rated. This means they have an extra barrier of insulation built in the roof to keep cool air inside in the summer and warm air inside in the winter. However, this extra layer of insulation (I have no idea what it is made of) blocks cell phone signals quite well......pathetic.
