# APN Configuration

ConnectedYou SIMs require you to configure APN in your devices most of the time (there are some exceptions). It's quite simple:

* **Name**: Any name you prefer
* **APN**: Based on your profile, see information below.
* **Username/ Password/ other**: Leave blank/ default

How do you know which APN to use for the SIM you have? You can refer to the APNs mentioned in CY console:

In general though, the APNs are usually constant for a set of SIMs provided by a Connectivity provider:

* TATA SIMs/ profile SKUs: move.dataxs.mobi
* Monogoto SIMs/ profile SKUs: data.mono
* Telna SIMs/ profile SKUs: rainbow
  * You can configure APNs closest to your deployment to reduce latency as well. In most cases, rainbow should be applicable, but otherwise the following are the options:
    * Americas - altanwifi
    * Asia - kroly
    * Europe - rh
