I’ve increased my plan to allow me to access the internet on my Google TV.  With hindsight this was a very foolish thing to do as the phone signal is so poor the connection is unreliable at the best of times - eg having to walk about the flat to get even one bar, then calls dropping when finally made, which usually results in me asking the people I want to call to instead call me!!

But I’m now on this 200gb plan using very little data.

When I put the SIM card in my wife’s iPhone it behaved the same as when it’s in my phone.  Frustratingly, she does have a tolerable signal and it is strong enough to watch the Google TV when on her Giffgaff Sim.

Advice please

Can I improve my signal?

A lot of things can affect the strength of your signal. Your distance from the nearest phone mast can make a huge difference. Large obstructions like trees and buildings (especially ones with lots of metal) can make your signal worse too.

If you're having signal problems here's a few tips to try and make it better:

• First of all, go for the tried and trusted method of turning your phone off and on again. Yes, it's obvious - but sometimes it really does work.
• If you're using your phone indoors, try going into different rooms to see if it makes any difference. Some rooms can get a stronger signal than others.
• If you want to get a little more technical, put your SIM card into another phone and test your network coverage. This will help you to work out if there's a problem with your phone or the network.
• Doing a factory reset can sometimes make a difference. Backup your phone's data first of all, then go into system settings and carry out a reset.
