Please can anyone tell how long does free account valid in twilio?
It’s free for 1year, but it also depends upon the credits you were having the account.
Twilio account is free for the first trail only. As soon as the trail expires one can create another account with different credentials.
I have already faced this problem, I immediately created one more account with my secondary mail id and phone number.
To solve such type of problems this is another tricky way.!!
The Twilio account free trial projects are given a small balance for limited testing and they allow only one Twilio number per trial account. So you have to upgrade the project when all trial balance is used and the account is valid until all the balance is used.
