All sms message is based on templates, please create your template and allow it to be approved before you send. Do not Send Spam or Fraudulent sms. it will not deliver and your account will be deleted.
add new template eg: Hello, ##MESSAGE##. that means that for every message you send it must start from the test Hello, (with the comma), then ##MESSAGE## can be any text and must have . (full stop at the end). eg using the template above:
Hello, Ben where are you please call me.
you can create as many template as possible. you can just add your entire sms message as a template, wait for it to be approved before you send the sms. SMS will be delivered with your Sender ID(if the number is in DND we use a random number to deliver it.)

We at ifIHearSMS are no different from you, we too would like the bulk sms service we buy to work so that we would not spend additional money making it to deliver. That is why we built our own bulk sms service, so that we too could use the service that we have.
