Then evaluate the signal strength in minicom with <code>AT+CSQ</code> | |||
You will get the result as <code>13.99</code> | |||
The first digit shows the signal strength: > 9 — satisfactory, > 14 — good, > 19 — excellent. Low and unstable CSQ values mean that the antenna is poorly positioned, carelessly connected, radio placement is unfavorable. | |||
If both checks are passed, but there is no connection, contact your provider (check in your personal account), you can check the SIM card in your smartphone. |
