China Mobile in Sichuan: SIM Cards, Coverage & Service Halls

Coverage extends to most towns, but signal thins out in remote mountainous stretches of western Sichuan (Garzê and Aba prefectures). Chengdu and the main tourist routes have reliable 4G/5G.

China Mobile generally has the widest overall network reach in China, including rural and mountain regions, so it's the safer pick if your itinerary goes beyond Chengdu into western Sichuan. China Unicom can have slightly better international roaming compatibility on some handsets, but for raw signal reliability outside the big cities, China Mobile is the stronger choice.

Yes — both Tianfu (TFU) and Shuangliu (CTU) airports have carrier counters in the international arrivals hall where China Mobile, China Unicom, and China Telecom all sell short-term tourist SIMs (typically 7/15/30-day plans) on the spot. You'll need your passport, and the process usually takes 10–15 minutes. Counters aren't 24 hours, so a very late-night landing may mean the desks are closed — an eSIM set up before you fly avoids that risk entirely.

Yes — Chinese regulations require passport-verified, real-name registration for any local SIM. In Sichuan that means either an airport carrier counter at Tianfu or Shuangliu, or one of Chengdu's 88 China Mobile service halls if you're already in the city. Physical SIMs bought in advance through affiliate partners like Talktiko usually come pre-registered, so you can skip the counter entirely.

For most short-stay itineraries — Chengdu city, the Panda Base, Mount Emei, or Jiuzhaigou, all under about 30 days — an eSIM covers your data needs without a hall visit. If you need a real Chinese phone number for apps like DiDi that require SMS verification, you'll still want a physical SIM.

Yes, China Mobile operates branches across all Sichuan cities, but this site only has a verified hall-by-hall directory for Chengdu so far. Use the locations index to search for a branch in another city, or check with your hotel or local China Mobile customer service.
