What mobile phone card do seafarers use on international routes?

Give you the most professional answer.

The first is the mobile phone. It is best not to use fake mobile phones. In some countries, SIM and fake mobile phones are unreadable. So it must be a regular mobile phone, even if it is just a small brand like Alcatel. Need to be reminded that for American cards, you must ensure that your mobile phone is a tri-band mobile phone. You can check whether it belongs to a tri-band mobile phone online. Most other countries do not have this requirement. In addition, it is better for your mobile phone to have WIFI function, so you don't need to buy a calling card for business in many places, because many countries will have free WIFI for you.

Secondly, it is a mobile phone card. It's best not to use iphone, because most countries don't provide small cards for iphone, only ordinary small cards. Nowadays, calling cards in many countries can be seen when you buy them. They are all tried in ordinary card slots and small card slots, but they are not suitable for iphone. When workers or agents come to Hong Kong, they will take the initiative to contact the crew to promote calling cards. Tariffs are generally cheaper, and only a few countries are particularly expensive. It is worth mentioning that the more developed the country, the cheaper the tariff. I'm in Australia now, and it's basically 6 minutes per minute to call back to China.

Finally, in general, the satellite phone on the company ship can be used by individuals, but it is more expensive, many of which are more than one dollar a minute, but you can use it at any time in an emergency. It seems that your company doesn't provide free mail service. At present, many companies, long-distance ships and companies will provide free personal mail services for all-weather crew members.
