I'll have to figure it out. I bought a new I Phone 5s and the De Lorme In Reach Explorer Sat messenger. Apparently you can bluetooth through the I Phone to the Messenger, and get satellite texting capabilities on the Phone. My buddy has it and it works great. Should come in handy for longer range fishing/hunting not to mention all my partner boats have the inreaches. Amazing how you never hear guys on the VHF anymore. All info is passed via DeLorme Inreaches.
