NEW YORK (TheStreet) -- It doesn't matter if you pay for the fastest 4G network if you get awful signal inside your house. But you may be able to do something about it without breaking your two-year contract.
Mobile carriers are more anxious than ever to keep customers, and often will provide signal-boosting devices and service for free. But that's only if you've tried everything else.
Those darn brick walls -- or nearby trees and mountains or other vents and wiring inside the walls -- could be blocking valuable signals to your basement. But if there's a tree blocking your direct sight to the nearest cell tower, consider these tips before chopping down trees or knocking down walls.
Talk to your mobile carrier: While not a new tip, this is the first place to start when your home lacks a signal. The mobile industry is super-competitive and many of the companies will do anything to keep you.Check with them to see what they'll offer you. My own carrier suggested replacing the SIM card (the existing one could be outdated or corroded) and turning on "data roaming." Also, keep your phone charged (power improves signal strength) and get rid of the metal case (weakens signal). The carrier may even send a technician to your neighborhood to check outdoor signal strength. If they discover that is terrible, they'll know what to fix first. Try a new app: If you've got a smartphone, there is a plethora of apps providing tools to pinpoint nearby cell towers, display your phone's signal strength and check who has the best service in your neighborhood. Some apps reboot your phone, recalibrate the wireless radio and automatically connect you to the strongest signal. See "Apps to help improve smartphone reception" for reviews of related iOS and Android apps. Get a 4G boost: Signal boosters use power to amplify a signal indoors and have been around for years. They typically consist of an outdoor antenna and an indoor amplifier. Only recently have 4G boosters hit the market. One of the device leaders, Wilson Electronics, just expanded its first line of 4G mobile signal boosters. Its new Sleek 4G line (a two-piece device with an antenna that sticks to a building's exterior window or car roof, and a second piece that stays inside to boost signal) offers 20 times the power of a typical cellphone signal. Other new 4G signal boosters are now available from Wi-Ex and Cellphone-Mate. Also, check with your carrier for a possible freebie. T-Mobile, for example, offers a Cel-Fi signal booster for cheap or free if you're willing to commit for two more years.
