Hi @Chniduh
You should be able to sign-up for your account (if you have never signed up before) no matter what phone is being used. Azure has a pretty robust system for picking up if you are a previous customer and will not allow you to sign up for two or more free accounts.
Statement from the FAQ:
The Azure free account is available to all new Azure customers who haven't previously had an Azure free account and received a USD200 credit.
