Switch to Another Carrier
If nothing else on this list has done anything to improve your cellular reception, go ahead and check the coverage map for your specific carrier. You can find maps for AT&T, T-Mobile, Verizon and Sprint. (If you have another carrier, just try Googling their coverage map or contacting them directly.) If it looks like coverage is spotty in area, consider switching to another carrier. That’s obviously a big decision, but when it comes to cellular reception at your home, you may prioritize where your house is located over which carrier you use.
