| Steps | Cause(s) | Solution(s) |
| 1 | This problem is generally due to the unavailability of the 3G/4G/5G data cell network. | Check that the cell network (3G/4G/5G logo at the top of the screen) or wireless network is enabled. Is your wireless or cell network signal strong enough? If the problem persists, move on to the next step. |
| 2 | This problem may also arise if you have reached your mobile package's data traffic limit. | Contact your mobile phone operator to check your subscription and consumption. If you are in a foreign country, you may need to enable roaming mode. Your operator may apply a surcharge for this service. If the problem persists, move on to the next step. |
| 3 | If the problem persists after checking all the aforementioned items, we suggest contacting our Customer Service department. | If this is unsuccessful, contact AMA Customer Support. This topic explains the appropriate procedure. |
