QB and SMS

There are ways of doing it natively using emails; but there is also a Juiced Technologies' tool to do this as well if you want something more sophisticated.

Sending sms notifications via email involves knowing the correct format for each phone providers network to send sms throught email.

Case([Cell Provider],
"AT&T",[Cell # (as number)]&"@txt.att.net",
"Verizon",[Cell # (as number)]&"@vtext.com",
"T-Mobile",[Cell # (as number)]&"@tmomail.net",
"Sprint PCS",[Cell # (as number)]&"@messaging.sprintpcs.com",
"Virgin Mobile",[Cell # (as number)]&"@vmobl.com",
"US Cellular",[Cell # (as number)]&"@email.uscc.net",
"Nextel",[Cell # (as number)]&"@messaging.nextel.com",
"Boost",[Cell # (as number)]&"@myboostmobile.com",
"Alltel",[Cell # (as number)]&"@message.alltel.com",
"MetroPCS",[Cell # (as number)]&"@mymetropcs.com"
)

I have this working in one client's app.

Just toss it out there that integration tools like Workato have out of the box features like this - and build in additional features like logging what was sent when, to who etc. A third party tool will give you a little more visibility overall when you're trying to outbound communication

One more suggestion: use Quick Base's Webhooks and a service like Twilio to send SMSs. If you don't know the recipient's carrier, this is probably the cheapest option (though you'll still need to pay Twilio per SMS).

Juiced has an add-on which will send and receive texts.  I have used it and its very solid. Never had a problem.

Check out the ABC QRCode Example app on the exchange. It uses Google API to send SMS.

Here is the code in the formula rich text field that accomplishes the SMS:
"<img src=\"http://chart.apis.google.com/chart?chs=200x200&amp;cht=qr&amp;chl=SMSTO%3A"; & [Mobile] & "%3A" & [SMS Message] & "\" alt=\"Send text message to the contact\" title=\"Send text message to the contact\"/>"

// This code was originally generated at https://www.the-qrcode-generator.com/
// The above link contains URL encoded characters.
// Legend:
// %3B ;
// %3D =
// %3A :
// %0A space

Twilio and Pipelines or Zapier can be used to do this,  if you're savvy to build your own functions custom.    I'm currently building this functionality into our system.
