Sorry If I have been confrontational. I did misread your sentence,
Just as hypothetical example, leaving alone internet SMS services which grant receptions. Given the louse normatives regarding rechargeable SIM cards in most countries it could be even less expensive then getting domains and vps for a spammer to do unsollecited registrations with sms services rather then mail...
Which is why if you want something to be secure you need multiple layers of protection, For instance Google puts together Mail + SMS + other stuff (and it's far from being foolproof itself).
You may not agree legitimally, but still saying SMS verification alone is better then E-Mail verification is misleading at best. The fact it works for you it doesn't mean it's an optimal choice and should put other methods apart.
