Extend the whatsapp subscription by one year using a landline number

If you do not want to pay for whatsapp subscription, you can extend the license for one year with this small workaround. You need to have a landline number for this to work.

1. Delete the expired account. This option is available in settings>Account. You need to type your number before you can delete the account.
2. Press change number available in settings>Account. 
3. Type in the landline number. Whatsapp will attempt to verify this number by sending SMS. Since this number is landline, there will not be any SMS received.
4. Whatsapp will wait for 5 min. After 5 min is expired, whatsapp will give you an option to call you at the landline number with the confirmation number.
5. Confirm to call the landline number and input the confirmation received on landline number.
6. You got one year free subscription to whatsapp.
