Suggestions for SMS providers / APIs

Let’s collect possible easy-to-use SMS (aka “text messaging”) providers (and APIs of corpse) in this thread.

Those I know of (reliable ones, which are free as you go / prepaid, no contract mumbo-jumbo):

• Sipgate API (Germany / UK / Europe; prepaid )
• TextMagic API (Europe, US, UK; prepaid)
• Nexmo Verify API – they got an SMS API as well
• SMSTrade Gateway API (Germany / Europe)

And of corpse you may build one yourself:
Howto Send/Read SMSs using a GSM modem, AT+ commands and PHP 🙂

Looks pretty simple to me though.
