# Set Up Link Mobility Account

Before you begin, you will need:

* A paid LinkMobility **SMPP** Account.

{% hint style="info" %}
This is **not** the same as your REST API Account. SMPP is a protocol used to send SMS.
{% endhint %}

* Change each LinkMobility account's parallel connection allowance to 10 (the default setting is one). This is so that CrossEngage can run multiple nodes for load balancing.
* Account rate limits of at least 100 requests/second.
* A CrossEngage account.
* User data (including phone numbers).

**Configuring user attributes**

We suggest you use the “traits.phone” user attribute when using LinkMobility. You do, however, have the option to choose which attribute stores your users' phone numbers when setting up the integration. The phone number of the user should be in the international format. (example: +49 1234 56789 or +49123456789)
