The smartphone does not see the SIM card

SIM card: a key element without which the phone cannot see the network. And therefore, if the phone refuses to ring, then the connection between the SIM card and the device does not work.

Why the phone does not see the SIM card

"Simka" and the phone may conflict due to the fact that the device is "locked". If you bought a phone for a promotion from an operator, with a preinstalled SIM card, and try to insert a card from another operator, then there will be no connection. The phone is coded to work with a specific operator and does not see the "someone else's" card. There are two options: either leave everything as it is and use the services of the operator for which the phone is coded; or contact the craftsmen who will play around and remove the encoding (if, of course, they can). After this procedure, the phone should accept other SIM cards without any problems.

Faulty SIM card or phone

Problems with the slot and contact can be if moisture gets into the phone or it is dropped. In the first case, the contacts in the slot are oxidized, and in the second, mechanical damage is possible. In either case, you need to go to the service center.

If a trouble happened with a smartphone that you have been using for a long time, then perhaps the reason is poor contact between the SIM card and the phone. Therefore, the telephone does not accept the card. We remove the back panel from the phone, if the SIM card slot is located under the battery, then we take it out too. Maybe the card has moved a little and the contact with the phone's panel is broken. It is best to check the status of the contacts immediately. There may well be dirt or dust on them. We take out the SIM card from the slot, if necessary, clean the contacts and insert it back.

If you have a smartphone in which the panel cannot be removed, then the sim card must be wrapped in paper so as to leave free contacts and insert into the slot.

Contact can be broken not only by dust and dirt. Over time, the contact between the slot and the card may loosen. For example, due to the fact that the case is loose or the battery does not press well on the card slot. Then you just need to take thick paper, fold it several times and place it between the slot and the battery.

Number validity period

Alternatively, the phone number has expired. This happens if you haven't used your phone for a long time. In this case, you need to contact the operator and restore the number. Another option is that the SIM card has deteriorated. Everything in this world has an expiration date. To check this, insert it into another phone. If the phone does not detect the card, contact the operator to extend its validity period. Or buy a new SIM card.
