I live in the Midwest, where all cellular carriers have spotty service. However, I have noticed that Virgin is worse than previous phones that my wife and I have used on US Cellular and Sprint. Even at best, I can only get 1x service and no 3G. When driving through the corner of Iowa, I will completely lose service for at least half of the drive.Over the holidays, we will be driving deep into the Southern part of Louisiana, and I would like to have service on the road just for security. I have been reading about PRL swaps, and am curious as to whether this could help me. Is this the best way of improving service? Also, I am a Mac user. How does the PRL swap process change?
