Article: These include laptops, iPads, microwaves and other electronics. Turn the WiFi and Bluetooth off, too, and see if that helps devote more of your phone's resources to finding a signal. Turn off these other devices if possible. If that doesn't work, consider turning your phone off too and turning it back on again shortly thereafter. Sometimes a little reboot solves just about any problem. Your cell phone uses a lot more power when connecting a call than when it is on standby. Often, your battery can be strong enough to attempt a call, but not strong enough to find a signal. If you find you are having signal problems, consider your battery and get to charging. Mobile phone antennas are designed to project a signal outward, perpendicular to the long axis of the antenna. As such, mobile phones seek signals in a donut-esque shape around the antenna. Normally, when a mobile is held upright, this is not a problem. However, if you are holding your phone in a strange way, such as on its side or upside down, you will hinder the operation of the antenna. Hold your phone upright to guarantee that your phone can "see" your carrier signal.  On most newer phones the antenna is located at the bottom of the phone, so if you are experiencing signal problems on a newer phone turning it upside down will boost your signal. On the older phones, the antenna can usually be located on the rear upper area of the phone (near the camera). Make calls and connect to internet from your phone as normally you would. If your mobile phone supports UMA, you can use the wi-fi as your cellphone signal where you don't get GSM signal coverage or areas with poor coverage. There are also some apps that are free to download, such as Viber, which call using Wi-Fi Not all devices and carriers support UMA calls. Some Blackberry, Androids and a few other phones support UMA, and it is becoming more and more common as technology improves.

Keep your phone away from other electronic devices that might interfere with your reception. Try to keep your battery charged to 2 bars or higher. Hold your phone correctly. Use Wi-Fi as your cell phone signal.
Article: Lay a mat or old sheet down on the ground to protect the seat and bars from dirt and scuff marks if you've turned it upside down. Make sure you are in an open, well-ventilated area that can get wet without ruining anything. You don't want to blast any of the dirt away, you simply want to wet the bike and remove and loose dirt and grime before you start scrubbing. Never use a high-pressure hose or nozzle setting. This can force water into your components, causing internal rusting or de-lubricating important junctions. If you desire, you can also add a bike specific cleaner, but avoid using ordinary dish soap as it typically contains salt which can corrode parts of the bike, including the frame. You will want to use a different bucket and sponge than the ones used for your drivetrain. Grease from the chain and cassette will get on your frame if you don't use fresh supplies, ruining your clean-up job. You want to get into those as much as possible and you need to get on the inside of the frame with your sponge. The wheels make it difficult to clean the parts of the bike closest to the ground and tire, which are often the dirtiest areas. The tires, which will become dirty again the second they touch the road, do not need to be cleaned. But the metal rim of the wheel can pick up gunk that gets in the way of your breaks. Use the abrasive side of a sponge to clean off the edges and lightly wipe down each spoke so your bike looks clean and sparkly.   Use a toothbrush to scrub the hub-- the small cylinder in the center of the wheel -- and the nuts and bolts on either side of it. If you want to clean your tires, or you see large chunks of mud in the treads, use a big, heavy bristled brush (like the one sold with a dust pan) to clean them quickly and painlessly. The rear cassette is the collection of gears on the back of the bike. While you cleaned it briefly when you cleaned the drivetrain, you should take the time to make sure it is spotless when doing a full bike cleaning. Drip some soapy water into the cassette, then use a clean rag to "floss" in between each of the gears and remove any extra gunk built up deep in the cassette.

Rest the bike in a stand, on a rack, against a tree, or upside down. Spray down the bike with a low-pressure hose. Fill up a bucket with warm water. Remove your wheels. Wipe down the rims of your wheels. Use a clean rag to get deep into your rear cassette.
