Another option is buying a cellular booster antennae, they can hook right into the camera and you can be good to go. I have a weak signal area on my property that I wanted to place a cell cam, at first it didn't have any signal and my phone was really spotty back there. Bought an antennae for truckers and connected it, went from zero bars service on cam to 3 bars and great service. The one I bought was 50 bucks, made the camera useable and was well worth the money. Wilson/weboost. It was service specific so make sure you get the corrrct one for your service provider, but super easy to install and use (unscrew original antennae and screw in new one, it really was that simple).
