Been with Verizon a while now, after switching from AT&T and their poor reception. Anyways, I have a iPhone 5s and have been making phone calls while walking around in my neighborhood (zip: 90027). And I've had a real hard time this last month. Dropped calls or poor reception, etc. I am wondering if there's anything I can do to my phone to improve the reception when I walk around the neighborhood and catch up with my family back east. I know one bit of advice would be to "not move while you're on the phone" but that's not exactly what I'm looking for. ¡Gracias!
