Three of us (myself and kids) will each have phones. Mainly for contacting each other in case of unforeseen separation. Also for the boys to text/talk to their mother back home. We will have WeChat. The phones are all unlocked. What type of sim cards should I buy, on arrival, to enable this?
I understand that Unicom is a good service provider. Should I sort this at airport on arrival or in city centre? If the latter, is there a shop near Houhai?
I will also have my MacBook which I will use for email and general surfing. I can get by without Google. Do I need to get a vpn?
Any other advice for a not-too-tech-savvy traveller?
