I am temporarily living in an area where I don't get very good Verizon service at my home, but I do at work and at school. Anyway, while at home Verizon uses US Cellular towers to provide me with cellphone service through their extended network. I have noticed that my Ipad doesn't show the extended network at all, and a lot of times while I am at home it either says searching/no service, or maybe 1 bar of Verizon (pretty much no service and when it is on extended network it says extended). So is their extended network just through their phones or what is the deal with that? Thanks in advance.
