We all know the feeling - you go to use your phone only to find there's no signal. On the train - or at home, it's a bigger problem in London than you might imagine.
According to new research, a third of Londoners are plagued by blackspots.
After spending 6 weeks collecting and analysing data from inside London homes Global Wireless Solutions found:
- 35% of Londoners have some kind of mobile blackspot in their home
- 29% told pollsters they 'regularly' have issues making and/or receiving mobile calls from home
- More than 40% of the Londoners polled by GWS for its survey said that mobile data connectivity issues had 'definitely contributed' to their decision to switch operators
