Yesterday, I went to the four main telecom companies in Macau and have gathered the prepaid sim information. Wherever I go, I must buy a phone SIM card to get around, so I can use the google map, search for information, and most importantly stay connected on my Facebook, WeChat, instagram so and so etc.
You can buy these prepaid cards at 7-eleven or OK convenient stores. I think CTM do have phone SIM card vending machine at ferry terminal and airport, but quite often out of stock. If not, you might as well need to go to their store to buy. All these four telecom companies have branch stores that are with 10-20 minutes walk away from Senado Square.
I have highlighted each company SIM card details as below, which you may refer to my recommendation if you are staying in Macau for 1 – 3 days. After the chart, I have attached the data plan images, and the source link which you can explore for more details.
You can find souvenir shops easily at the tourist sites or museums. You can buy fridge magnets, t-shirts, pen, umbrella, or all sorts. As for snacks, we have beef jerky, pork jerky, egg rolls, almond cookies, …etc.
