I was just looking at Line2 which looks like it has more features and better pricing. Anybody tried any of these services? Can they reliably replace a phone?
From talking to users, we find people prefer SendHub because of the reliability and customer support. Also, SendHub has a free plan and for businesses we make it easy to get control of your employees communication, while keeping costs down.
Just noticed that SendHub has an easy API for SMS.
We have a lot of businesses using via the api, examples include: lead gen, crm, subscriber notifications, marketing and even competitions.
