How to get 1 bar calls/texts to go through on iphone

Trying to send a text or make a call with one or no bars of service? Are there certain "dead zones" that every once in a whole you get something through but rarely? Try flipping your phone upside down

Also no matter what direction your holding the iPhone, make sure you grip the lower half as to not block the antenna. You will notice that places where you normally couldn't send texts now work!
