# Physical SIM #2

{% hint style="info" %}
This is the second most reliable method. It ***should*** work for most carriers; T-Mobile, Boost, Google Fi, AT\&T, etc.
{% endhint %}

## Steps:

1. Take your inactive SIM card and put it into your iPhone
2. Edit the **Phone Number** to be your main phone number without the plus
   * Instead of +1 1234567890, enter 1 1234567890
3. Take out your inactive SIM and put in your active SIM into the iPhone **(Please wait about 10-20 minutes to make sure that Apple has your number registered to iMessage.)**
4. Turn on **Airplane Mode**, but keep the **Wi-Fi** off
5. Take out the active SIM card and replace it with the inactive SIM card with the edited **Phone Number**
6. Turn off **Airplane Mode**, but turn **Wi-Fi** on
7. Keep your iPhone always powered on, plugged in and connected to Wi-Fi
   * *Keeping the iPhone always on may not be necessary, I'm currently testing it and I haven't been deregistered yet!*
8. On your Mac, make sure to accept the "**new number**" being added to your Apple ID

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://atbluebubbles.gitbook.io/guide/new-methods/getting-your-phone-number-registered/physical-sim-2.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
