Content

We do understand that it may seem a good idea at first to use content like:

  • This is a test
  • Hello world!
  • Testing for company ABC
  • Hello X, please let me know if you receive this message

However, we do not recommend to use such content for your test. The world of SMS is complex and content may be filtered at several points between you and the handset, which you use to test delivery.

Above examples might be recognized as P2P traffic (People to People) and therefor might be blocked e.g. by the local MNOs (mobile network operators). 

P2P traffic is not allowed and might result in a permanent ban from MNOs or on our platform.

We recommend to do your tests with the exact content examples in the original language and using local characters (if not English) that you intend to use later for production.

Sender ID

The same conditions as above apply here as well.

Recipients

We recommend you use real phones with SIM cards. Testing with virtual/rented numbers may or may not produce good results.

We also do not recommend sending multiple SMS in a short time to one phone number. Traffic might be blocked/filtered for flooding.
