Take the subway in Singapore, and there is also the issue of invoices.

Yes, just use the MRT to buy an EZ link card. Go to any passenger service office next to the MRT and tell him EZ link. 15 yuan, there seems to be 7 stored values in it. I'll give you a receipt. You have to make sure that there is a balance of 3 yuan in it by swiping the card through the MRT, so you basically need to recharge it once a day. You can go to the place where you can buy a card, that is, the office next to the entrance of each MRT and tell him how much to charge, usually 10 yuan, 20 yuan. You will be given an invoice, you can keep it for reimbursement, or you can go to the general ticket vending machine next to you to recharge it. You can choose Chinese, which is very convenient. Finally, there is an option to print invoices. Don't forget.

Don't go to the open-air food street for dinner. Many of them have no invoices. Of course, there are invoices for going to chain food streets such as Koufu, Kopitiam and FoodRepublic. If you don't offer it to you, you can ask him for it. Go to a restaurant or something. Needless to say, it's all about the invoice.

If you use a mobile phone, it depends on whether your company will reimburse roaming charges. If you can, of course, it is better to use your domestic number. If it is not reimbursed, you can go to the counter of the local operator to buy a SIM card after you arrive at Changi Airport and leave the baggage claim hall. Ordinary SIM card and nano sim card can be provided for iphone. It doesn't matter if you don't buy it at the airport. You can go to any 7- 1 1 or operator's store and buy a calling card with your passport. When I first came to Singapore, I used SingTel from Singapore Telecom. Call China for 8 minutes from 8: 00 pm to 8: 00 am, during the day 19. There are three companies to choose from, SingTel New Telecom, StarHub Galaxy, the first M 1. After buying it, you can ask the clerk how to make an international call. The description of the sim card is also in Chinese, so you can study it carefully. I haven't bought this prepaid card for a long time. The sim card should be 15 yuan, which contains the phone bill of 15 yuan. If you need to recharge, you can buy recharge cards in supermarkets or communication shops, not in small shops, so as not to provide invoices.
