When they work, mobile phones are a piece of modern magic that we don't give a second thought. But when we have signal problems, they turn into a heap of overpriced junk that leaves you wondering if a couple of tin cans and a piece of string would be better. Fortunately there are a few steps you can take to improve your chance of getting a good signal.
Switch network
While network coverage is much of a muchness in densely populated areas, things are a lot different in the rest of the country and you may well find that switching networks makes a big difference. Each of the major networks has an online coverage map that gives a good general picture of the reception you'll get in your area, though it's not a guarantee.
Remember that there are only actually five networks in operation (Orange, O2, Three, T-Mobile and Vodafone) and that all other providers use one of these networks (eg Tesco Mobile uses the O2 network) so you may need to check which network to look at. Remember also that Orange and T-Mobile have a sharing agreement so most customers on one network will have access to the other as well.
Unfortunately if you are already signed up to a contract it can be very tough legally to get out of a deal because your coverage is poor or non-existent. Doing so is really a combination of luck and kicking up a stink with a provider.
Femtocell
Femtocell is a little gadget designed for people who have trouble getting a good signal indoors, such as in large houses with thick walls or those in blocks of flats. It's effectively a tiny version of a mobile phone mast that plugs into your broadband connection and provides a strong signal on your house. The name varies (for example, Vodafone markets it as Sure Signal), as does the pricing. Generally you are looking at around £50, though you may get a cheaper or even free deal depending on your phone package.
Battery strength
Phones use a lot more battery power when connecting to a network, to the point that a seemingly working phone may not have enough juice to find, make and keep a working connection. Most modern phone batteries can be recharged at any time without the old-fashioned "memory effect" (where not running them down completely could affect battery life), so it may be worth charging them up whenever you get the chance.
Workarounds
Search online and you'll find dozens of supposed tricks for boosting reception, most of which involve makeshift antennas in one form or another, from paperclips to empty drinks cans. Most of these should be taken with a pinch of salt, but they may be worth a try as long as you make sure not to do anything that could damage your handset.
