What SIM card should long-term workers use along the coast of Africa? What is the local SIM card in Africa?

You can use GSM mobile phones in African countries by purchasing a local SIM card.

GSM has signals in most countries and regions in Africa, and I often go there for business. However, international roaming charges are very high, and domestic calls are generally from 29 yuan to 59 yuan per minute. But receiving domestic short messages is free, but sending or replying domestic short messages is 1.99 yuan. In the host country, making local calls through GSM is 5.99 yuan per minute, and receiving domestic calls or mobile phones is 5.99 yuan per minute.

The best way is to bring your global phone, so that you can keep in touch with China. If someone sends you a text message, you can receive it immediately and receive it for free. When I call you in China, you can also ring the bell immediately, depending on the situation, whether it is an important person or your leader looking for you, or other unimportant calls. If it is a very important person or leader, just answer directly, no matter how expensive! If it's not very important, you can choose not to answer or call back with a local mobile phone or phone, which is also very cost-effective. Besides, generally speaking, foreign mobile phones are cheaper than China Mobile or China Unicom.

I usually buy a local prepaid mobile phone card at the airport when I arrive in a certain country, so you'd better bring an old mobile phone when you are on a business trip, buy a local card when you arrive, and inform your colleagues or leaders at home quickly. In that case, if they want to find you, they can call you through the company's international call. When you have something urgent to report to China, it is much cheaper to use this local mobile phone. Generally, the mobile phone card I met in Africa can make domestic calls or mobile phones, and one yuan (7 yuan) can make domestic calls for more than 3 minutes. Do the math: It's the cheapest to make a domestic call with GSM from there, 29 yuan per minute! People don't take money from 3 yuan. . .
