Question: I'm using Firebase Phone Auth to identify the user, the sms is received but I need to change the SMS sender name (Not the template) in mobile, is there anyway to change the sender name or the messaging service?
The sms is received like:

`Phonecode
106109 is your verification code for MyAppName`

what I need is:

`MyAppName
106109 is your verification code MyAppName`

Answer: 
the app name displayed in the SMS can't be changed manually (neither can you modify the template).  

**The app name is retrieved from the play store/app store once the app is live in the store**.  

This wasn't 100% clear to me after reading Rumit's answer.

here is the response from the firebase support about this matter:

> 
> The SMS messages draw the app's name from the App Store / Play Store.
> Once an app is published, the correct name should start appearing.
> There may be a small delay (a week or two at most). So, this is an
> expected behavior if you published the app a few days ago.

> (which is the name shown as the %APP\_NAME% value on the SMS template).
> Firebase pulls %APP\_NAME% from the Play Store based on this
