What are the costs?

I am currently in Spain and received the following two sms's from MTN since my arrival:<br> <br> From: +***<br> Received: Oct 10, 2015 13:06<br> <br> Roaming rates on Movistar (ESP)<br> Calls/min<br> Local R70.00<br> SA R70.00<br> Receive R2.50<br> SMS<br> Local R7.50<br> SA R5.00<br> Data/MB R75.00<br> Data increment R7.50kb<br> <br> and<br> <br> From: +***<br> Received: Oct 19, 2015 21:47<br> <br> Roaming rates on Movistar (ESP)<br> Calls/min<br> Local R5.00<br> SA R5.00<br> Receive R5.00<br> SMS<br> Local R5.00<br> SA R2.50<br> Data/MB R10.00<br> Data increment R5.00kb<br> <br> Quite a difference between the two so I asked MTN via their website to explain but no response. So what is the roaming rate and please explain the two text messages?<br>
