Where to travel and how to use the worry-free service package?

Hello, dear, I have learned where to travel and how to use the worry-free package. Steps: 1. The overseas traffic is as low as 60%. Overseas traffic is 6-8 fold all the year round, and it is basically 60 fold on holidays, which is particularly cost-effective. Take the purchase of local traffic packages in Japan as an example. Worry-Free Store APP offers two types of 4G roaming traffic packages, namely "Daily Traffic Package" and "Limited Package". At present, the daily traffic package is 60% off, and the daily traffic package is only 16.8 yuan, while Alipay only provides the daily traffic package, which not only has few choices, but also has no discount. The 1 daily traffic package is more expensive than the worry-free store. The more days you use worry-free, the more money you save. Second, new users can send 100 minutes for free calls, and all mobile Unicom telecom numbers can be used. Regardless of the mobile Unicom telecom number, you can get 100 minutes of free time when you log in and register for Worry-Free APP for the first time, and you can call the number in Chinese mainland outside China, which is converted into roaming charges, saving a lot of phone bills. The method of making a phone call is also very simple. Enter the "Call" entrance of Worry-Free APP, select China, and enter your mobile phone number to initiate a call. Third, it is also free to answer the phone when roaming internationally. Chinese mainland's mobile phone number opens "free incoming calls and text messages" in the 51-Worry APP, and all incoming calls and text messages of this mobile phone number can be answered free of charge through 51-Worry, without any roaming charges, completely free. From then on, I won't panic when I answer the phone calls from relatives and friends in China, and bid farewell to "losing contact" completely. If my answer is helpful to you, please give me a compliment (comment in the lower left corner). I look forward to your compliment. Your little efforts are very important to me, and your support is also my motivation to move forward. If you feel satisfied with my answer, you can click on my avatar for one-on-one consultation.
