IPhone 11 Weak Signal

@cjscottjr1  AT&T's Cell Booster is not a cellular booster but a femtocell. It uses your internet to connect to AT&T's Mobility Servers. To answer your question, yes it will work with the iPhone 11. The Cell Booster is LTE only and requires a post paid AT&T account. I would try WiFi-C (WiFi Calling) first to see how that works before investing in the Cell Booster. You can return it if it doesn't work but there is a return window to pay attention to. It's a one-time purchase.

Read my AT&T Cell Booster Tech Guide, the link is the first one in my sig line, for detailed information on the Cell Booster.

Ok we don't have ATT Internet Service... any suggestions as to how we can get more than 1 bar of service at the 60480 zip code? We currently have phone set to WiFi.

Thanks,

@cjscottjr1  You don't have to have AT&T internet service. The Cell Booster will work with any carrier but it requires a land-based internet connection (cable, fiber, or DSL). It can work with Starlink but wireless or satellite internet service is not supported by AT&T so if there are any issues you are on your own. WiFi-C is different from WiFi. Your phone needs to be WiFi Calling capable and your AT&T cellular account needs to be provisioned for HD Voice (AT&T's version of VoLTE). 

You can always look into actual cellular boosters. The second link in my sig line is a pretty good primer on cellular boosters.

If none of that works, then you'll have to switch to a carrier that offers better coverage in your area.

Hey @cjscottjr1,

We hear you, and let's share the information you require! 

To answer your question, AT&T Cell Booster are mini cell towers that improve cell signals by using your current internet connection, so Signal boosters work with all and 4G LTE networks on all iPhones and other smartphones as well.

@cjscottjr1  The link that ATTHelp posted is for the AT&T Cell Booster, which is what we've already been talking about.

Who is your ISP and what kind of service do you have? Do you have a post paid AT&T cellular account?
