Why does O2 think I am in Dubai?

[LAM]

Not sure I'm posting this in the right place but maybe someone can advise. I was driving in Surrey earlier when I got a flurry of texts that appeared to be from 02 Roaming saying Welcome to Dubai and advising me of Roaming charges etc. I didn't open them because my scam radar is on red alert right now. But now I'm worried I'm going to get charged or that might phone security is not tight somehow. 

Why would 02 think I am in Dubai from the South Downs?

You should call O2 to see where the system thinks you are.

Advice from an O2 Guru regarding a way to get through:
If you call 202, when it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.

Welcome to Dubai?

Slim chance of that in the current climate!
