Transfer telegram from one device to another, I created a new telegram account and I need to cancel

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
Could you please clarify, do you need to delete an accidentally created second Telegram account?

Are you currently signed into the new account?

DO you have a Telegram app installed on your device?

Do you have access to your old phone number?

You cannot use your old Telegram account if you don't have an access to the old phone number, *****.
Could you please tell me, you are currently not signed into your old account on any device, correct?

Okay, great.
Open the Telegram app and tap the three horizontal lines menu button at the top-left corner. From the menu that appears, tap on “Settings” to access Telegram settings.

Yes, on the device where you are signed into your old Telegram account
Tell me once you've done so, *****

Could you please provide me with a photo of what you see on the screen?
To attach files to our chat you can use the button 'Attach' in the bottom-right corner of the chat with me

Okay, then just tap 'Settings' in the bottom-right corner of the screen, please

Under “Account” settings, tap on your phone number to change it. From the next page, press the “Change number” button to proceed further.

Thank you, *****

Tap on the 'Edit' in the top-right corner ,please

Once you tap on the change number, you will see a warning message highlighting that users will see your new number if they have it in their address book. Then, tap on “Change” to acknowledge the warning and enter your new phone number. Telegram will send you an SMS confirmation code soon after tapping the checkmark icon at the top-right corner. Enter it, and you have successfully changed your Telegram number.

Alright, then you will need to delete a new account first. Allow me a minute, please
Could you please open the Settings on your new device and new account?

As fas as I understand, currently you have an old Telegram account on an old device, which you would like to keep, and you have a new account on a new device, correct?

So, to change the phone number of your old account to the new phone number that you have, you will need to delete your new Telegram account first.
When you deleting the Telegram app you do not delete the account itself
So, could you please install the Telegram app on your new device one more time?

Would you like me to provide you with a link for it?

It's on your new device now, correct?

Okay, then please, enter your new phone number when it asks you for it

I’m glad I was able to get that sorted out for you. Before you go, is there anything else I can assist you with today?
