- Is the battery properly fitted, and are the gold battery contacts clean and dry?
- Do you have a spare battery that you can test in the device? Does it power on?
Battery & Charging Issues
- Is it properly connected? Are its contacts clean and dry? Check the charger.
- Is the device hot/warm or normal temperature? Check the battery temperature. If it is warm, let it cool before charging.
- If you see ? on the display near the charging icon, you cannot charge this battery. Make sure you have an Iridium approved battery installed.
- Are you using the AC wall charger to charge the device? Try charging using a DC (Car Charger).
- Is it an old battery? Battery performance declines after several years of use. Do you have a spare battery? If not, you may need to replace the battery with a new one.
- Is there any noticeable damage to the battery? Or is there any water damage to the device?
Battery Drain/Battery Performance Issues
- Are you in an area of variable coverage? This uses extra battery power.
- Is your antenna fully extended and correctly angled? Do you have a clear unobstructed view of the sky? This helps use less battery power.
- Is it a new battery? A new battery needs 2 to 3 charge/discharge cycles to attain normal performance. You may also need to leave it to charge overnight.
- Is it an old battery? Battery performance declines after several years of use. Replace the battery.
- Is it a battery that hasn’t been completely discharged? Allow the battery to fully discharge (until the phone turns itself off) and then charge the battery overnight.
- Are you using your phone in extreme temperatures? At extreme hot or cold temperatures, battery performance is significantly reduced.
SIM Card Issues
- Is the SIM card correctly inserted in the device? The cut-off/slanted edge should line up perfectly in the slot. Iridium 9555 - Inserting and Removing the SIM card – Roadpost
- Is the SIM card clean? The contacts of the SIM card may be dirty. Turn the phone off, remove the SIM card and rub the contacts with a clean cloth. Re-insert the card in the phone.
- Is the card visibly damaged or scratched? SIM cards are typically durable but if accidentally damaged, you may need a new SIM card.
- When you remove the SIM card, are the three gold SIM pins, all at the same height? If one or more of the pins is lower, free it by using very light pressure to pry it up with a pin or other small pointed object.
- Is the SIM card you are using active? You can check the "Manage Prepaid Refill" section of your account (for prepaid cards) or "Airtime Plans" (for monthly plans) to see what services are active, if you know the satellite phone number assigned to the specific SIM ICCID.
Network Issues
- Where are you using the device from? Are you outside? Ensure you are in an area with an open view of the sky and no obstructions close by. Trees, buildings, vehicles (including vessels such as boats) can act as forms of obstruction/interference.
- Is the antenna correctly positioned? Extend the antenna, lock it in and point upright towards the sky directly above in order to receive a signal.
- Did you power the device on, when you were inside? If your phone was powered on inside of a building or area with an obstructed view of the sky just prior to attempting a call outside, the phone may be temporarily in a power saving mode to conserve battery life. You may either wait for it to automatically exit the power saving mode within a minute or two on its scheduled interval or just simply turn off your phone and turn it on again to accelerate the registration process.
- Is there any noticeable damage to the antenna? Or is there any water damage? If not, complete a reset to defaults to attempt to resolve the network issues (Note: your information will not be deleted, but previously configured settings will need to be re-configured) Iridium 9555 - Factory Reset – Roadpost
Outbound Call/Text Messaging Issues
- Is the antenna fully extended and correctly angled? Do you have a clear unobstructed view of the sky?
