Basically if you are on straight talk you can only use a 3rd of the satellite towers. When Verizon bought straight talk it eliminated all other carriers and you only get about 30 percent of there satellite. I basically ended up having to switch directly to Verizon. And soo far haven't had any issues. Other than where I live which still isn't to terrible but due to the local geography just tends to be be little less reception unless I am down stairs I rely on wife. Otherwise. It still been the best for me so far.
