Twine wants us to be able to pay to get SMS Texts!
Here is a section from the email I was sent just recently -
As a Twine owner who's had problems getting their carrier to accept text messages from Twine, I wanted to let you know that we’ve developed an alternative. Previously, we were using the email-to-SMS gateway that carriers usually provide, but while free, it's proven unreliable.
We strive to make Twine’s experience as good as it can be, so we've added paid accounts in order to purchase "real" SMS (and voice calls that let your Twine speak what you type as a notification) which will work reliably with all carriers!

- it's pay-as-you-go, but if you aren't happy with it after trying it, we'll give you a refund for the account. Just let us know within the first month. Bonus: All texts and calls will come from the same number now, so you can save your Twine as a contact!
If the free SMSs are working for you, you'll still be able to send them using the email-based method (you'll just set it up in an email notification).
