We find the ATT mobley usually locks on with 3 or 4 bars at most campgrounds. The down speed is 850kb/s at 3G which is the max in rural areas. The published data rate for 3G is 2Mb/s, but I have never seen anything approaching that data rate except here in San Antonio, TX. 4G LTE is about 3 to 5 times faster but you have to near a large city to get that type of cell signal. A signal booster is going to change the signal strength but not the data rate. The data rate is determined by the network and cell tower. So if you aren't experiencing signal drop out, a signal booster isn't going to help.
