This question is more of technical one on how to contact escorts.
I'll be in London for 3 weeks Sept-Oct and want to set up some escort dates. I will have me iPhone but will use it for only connecting to the internet for web access and email. I will not be able to make calls. I also have downloaded WhatsApp and want to use it. I've noticed that many escorts prefer SMS or WhatsApp text messages. I don't think I will be able to use text messaging on my iPhone. So, I will need to use WhatsApp which I have never used.
So, how do I make sense of the London Phone Numbers. They all begin with +44. When setting up a contact on WhatsApp, do I include +44? For Example: "+44 123 456 7890". If I have access to a phone, what do I dial?
Thank you for any help you can give.
