Everyone will likely like interruptions in the mobile network and restrictions on Internet access. Various technical reasons among providers can cause such disruption. Especially if the subscriber has only one SIM card, then there will be no alternative to using another number. But buy eSIM, and the problem will disappear by itself. What is an eSIM card? A global eSIM card is a provisioned technology in which the card is embedded directly into the phone’s motherboard during the manufacturing process. That is, a module with a chip (built-in card) is a non-removable component of the gadget. You don’t have to purchase it at the operator’s store and install it in the phone slot. Because the eSIM is equipped with an operating system, microprocessor, and storage, it can be stored with several mobile numbers (from five or more) from different providers. Consequently, having more than one number, the subscriber will always be able to be in touch if one of the numbers fails in connection and has difficulty connecting to the Internet. Once abroad, the smartphone user has to enable mobile roaming in the phone settings. But such a connection is costly, and purchasing a local SIM card is only sometimes convenient: not knowing the language of the country and difficulties in choosing the right tariff can play a cruel joke. But with the use of local eSIM, these problems can be avoided. The features of the built-in card also include the fact that, once abroad, you will not need to overpay for mobile roaming. You can simply add the number of your local mobile provider and pay only for the selected tariff plan. As soon as this number is no longer needed, it can be deleted anytime. It is worth noting that the crypto used in virtual phone numbers allows you to maintain confidentiality: when applying, you will not need to confirm your identity, and communication over the phone is encrypted. Pay for eSIM with Bitcoins First of all, you need to be sure whether your phone supports this technology. It is checked in the settings: Connection – SIM card manager – Adding eSIM (in this case, there is a built-in card). To activate the built-in card (and, if necessary, purchase a new mobile number), go to the eSimsData website and order the service in just a few minutes. The application contains the following information: a country; mobile operator; tariff plan; mobile number (if you need to purchase a new one); email address. Next, payment is made (prices are beautiful), for which cryptocurrency (BUSD, Litecoin, Ethereum, Bitcoin) can be used. If necessary, you can use unique platforms such as Kinbase and Binance pay). The process of activating a eSIM card Any mobile card must be activated, and the built-in one is no exception. You can activate your eSIM at any time convenient for you (both before the start of your trip and during the trip). After the paid service, the user receives a QR code, and by scanning it, the built-in card is activated. Activation can also be accomplished by following the received link to the specified email address during the application process on the eSimsData website. Conclusion Considering the above, the built-in card allows you to be in touch and have access to the Internet all the time. Also, you don’t have to change it – write down the necessary numbers. A cheap eSIM will allow you to feel comfortable regardless of your location and will allow you to save on mobile roaming.
