Bringing your phone or buying a new one:
If you’re bringing an unlocked cell phone to China you should be able to simply buy a local SIM card, slot it into your phone, and be connected right away. You can try and get your phone unlocked here in China at local electronics stands, but our users have had mixed experiences.
Should you need to purchase another phone, consider how long you’ll be staying in China. If it’s only for a vacation, compare the cost of your cell phone provider’s roaming charges (which can be expensive) and the price of a “pay as you go” SIM Card which at the time of writing averages around ten dollars (60 R.M.B.) plus additional costs for minutes. Phones can also be bought here ( “dumb ones” are cheapest, smartphones cost as much or more as they would abroad, Xiaomi phones are a smart budget option). You can rent a phone but unlike electronics stands here those prices are normally not subject to negotiation.
