Wife got a text message saying she got free credit and to respond with CREDIT to activate it. Not realising it is probably a scam she replied.
Next message back was to telling to send an SAE to some address within 7 days to get the credit. No mention of how much. This was followed up by loads of you have been subscribed to various things.
They managed to take 15 euros in one day. Now I've done STOP to all of the messages but they keep coming from other numbers. Day 2 and over 20 euros and more messages.

Going to throw away the chip. But will be contacting COMREG. Here are the following numbers if anyone else is hit by it.
50015 - Offering the Credit.
credit - the return message.
8007 - Sub messages
57030 - Sub messages
353863810425 - various junk messages that you have joined ....
57030 also couldn't be replied to directly to do a STOP. Not that it matters.
