I am very interested in IRIDIUM 9575, yet I have a few questions which need clarification:
1. Does the 300 minutes can call globally? If yes, then how is it going to calculate the minutes?
2. Is the SIM card included?
3. Do I need to purchase another SIM card if I want to use this 300 minutes? Also is there a new number will be issued? Or I just need to add value to the SIM card?
4. If I happen to run out of minutes, do I need to purchase a new SIM card? 5. Do I have a steady number?
6. I am living in a big city which is surrounded with buildings as high as 300 meters. Will that be a problem for reception of the IRIDIUM 9575?
7. Can the SMS type in Chinese?
8. Is the warranty good for 2 years?
9. Does it come with caller ID function or signal stopping function?
