HI there, we currently use the rut240 in our remote monitor fleet, this is up in Alberta, Canada. SMS command functions have been turned on. The problem I'm running into is odd, I have a work Iphone that uses bell as the service provider and I have a personal Iphone that uses Kodoo (telus) as the service provider. When I send the sms commands using my work iphone (bell) the rut240 responds how it should and replies with a text. But when i send the same commands using my personal iphone (kodoo) the rut240 will not reply with a text message. Hoping someone out there may have a fix for this. Thanks
