1. Try to call to make or break reservations from a land line as a back up to your cell.
2. If you do not hear back from the people you tried to contact by cell they may have received a garbled or partial message or the message may have been dropped. Also, sometimes the messages don't drop down right away to the other phone. Don't assume that someone has received your message and try again if you don't hear back from them.
3. Make sure your battery is charged.
Things that happen to Cell Phones on the Big Island. 1. You lock your cell phone in the rental car along with your keys. 2. You leave your cell phone at the restaurant, pool, beach, etc. 3. You lose your cell phone somewhere? 4. Your two year old throws your cell phone in the pool, ocean, from the fifth floor lanai, etc. 5. You forget to bring your cell phone with you and find yourself lost (in the middle of a lava field, rain forest, or just on some road you decided to follow). This actually happened to four local boys who ended up having to spend the night in the mountains because it was to dark to find their way back by the time they decided to return home. 6. You finally get fed up with your cell phone altogether and fling it into the surf while doing a happy dance in the sand!
These are real scenarios and cell phones are expensive to replace so hopefully this will be a good reminder for cell phone users while they are on vacation.
