# Blok nomor telepon

## Nomor telepon

Jaringan GSM digunakan untuk menghubungkan terminal dengan pusat data (server), terutama saluran komunikasi GPRS/EDGE dan saluran SMS. Untuk tujuan ini, kartu SIM diperlukan pada perangkat GPS. Kartu SIM tersebut dapat dibeli dari operator telekomunikasi mana pun atau kartu SIM yang dibeli bersama perangkat, yang disediakan oleh оператор layanan pemantauan.

Jika Anda perlu mengganti kartu SIM di perangkat, Anda perlu memperbarui nomor telepon untuk mengubah pengaturan. Anda dapat melakukannya di panel yang sesuai:

1. Buka panel dan klik **Ubah nomor telepon**.
2. Tentukan nomor telepon kartu SIM yang terpasang di tracker.
3. Masukkan pengaturan APN dari penyedia layanan baru.
4. Setelah memasukkan pengaturan, klik **Simpan,** dan perintah SMS dengan pengaturan yang ditentukan akan dikirim ke kartu SIM.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://navixy.com/docs/user/id/guide/devices-and-settings/object-management/phone-number-block.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
