I arrived in Buenos Aires 2 weeks ago and signed up with a local service called Claro, got a chip, found APN's and was online. Pretty smooth. However, I was stuck on the Edge network. So, after almost 2 weeks of pulling hair out and searching on the web for the problem. I called VZW global services and they told me that Claro is who they use for there PRL (preferred roaming list) and that if I use Claro's service with my VZW phone I will be locked in Claro's Edge network and never get 3g or HSPA+. They told me to use a different service in Buenos Aires if I want to get 3g or HSPA+. So I cancelled the Claro service and went to the other companies and their plans totally suck. None of the plans here are really that good, but Claro had the best plan for me.
My first question for this thread is, if I root my phone will it remove VZW's PRL from my S3 and allow me to get Claro's 3g and HSPA+ connection, or is there a way to remove the PRL?
Please help me figure this stuff out. I'm seriously tired of digging through forums. I feel like I have been devoting so much of my energy to a silly phone.
