I am a webdeveloper specialising in providing websites, webhosting and email solutions for my customers.

I have signed up a number of my customers to Zoho Mail in the past, and a couple of these have grown into a paid package for Zoho CRM.

As I am then one setting up and managing their zoho email admin account I run into trouble when registering a new account as my mobile is number already registered towards another account.

I have now used up all my mobile phone accounts, my kids accounts, etc. and are therefore no longer able to add any more accounts.

I do understand that you probably introduced this "one mobile - one account" to stop spammers, but is there not any way for a legitimate customer of the free zoho accounts to setup a new zoho account without having to get another mobile number?
