We recently moved and the reception on my iPhone 5c is now terrible. Every time I call someone it is spotty and ends up hanging up on them. Reception is just OK when I go outside, but I can't make all of my phone calls from outside. And I don't want to get a landline. Any suggestions how to fix? Someone told me to call Verizon and get a "boost"...anyone know what this is? Thanks for your help!
