Opt-In Warning for Some International Carriers

Some International carriers require that their users subscribe to an Email to SMS feature before they are able to receive SMS messages this way. If one your users mentions that they are not receiving their messages, chances are it is due to this limitation.

Some carriers that need this include, Mobitel, Etisalat, T-Mobile (Netherlands), etc.

Setup Instructions

To use SMSnger, first require the library:

require 'smsnger'

Once the library is required, you need to run the setup like so:

SMSnger.setup(:from => "someone@example.com")

By default sendmail is used, but you can use SMTP as follows:

  :from => "someone@example.com",
  :mail_via => :smtp,
  :smtp => {
    :host     => 'smtp.yourserver.com',
    :port     => '25',
    :user     => 'user',
    :password => 'pass',
    :auth     => :plain,  # :plain, :login, :cram_md5, no auth by default
    :domain   => "example.com"

That's it! Now you're good to go.

Example Usage

  • You have to send in the phone number, without any non-numeric characters. The phone numbers must be 10 digits in length.
  • The two required parameters are the phone number and the phone carrier.
  • Here are some of the default carrier values:
Alltel Wireless   =>  "alltel"
AT&T/Cingular     =>  "at&t"
Boost Mobile      =>  "boost"
Sprint Wireless   =>  "sprint"
T-Mobile US       =>  "t-mobile"
T-Mobile UK       =>  "t-mobile-uk"
Virgin Mobile     =>  "virgin"
Verizon Wireless  =>  "verizon"
Vodafone Tokyo    =>  "vodafone-jp-tokyo"
  • Check lib/carriers.yml for a complete list of supported carriers, including international carriers as well.
  • If you want to set a custom from e-mail per SMS message, you can do so by doing the following.
SMSnger.deliver_sms("5558675309","at&t","message", :from => "bob@test.com")
  • You can set the maximum length of the SMS message, which is not set by default. Most phones can only accept 128 characters. To do this just specify the limit option.
SMSnger.deliver_sms("5558675309","at&t","message", :limit => 128)
  • You can retrieve just the formatted address to use in your own mailer.
SMSnger.get_sms_address("5558675309","at&t") # => "5558675309@txt.att.net"
