Some users fear moving to a new phone because of the complexity related to the SIMs, but with the technology of eSIM, the difficulty may vanish. Manufacturers now include this technology in mobile smartphones in addition to smartwatches, where it was initiated. eSIM is the embedded SIM, which is similar to a physical one. An eSIM supports all common networks, including 4G and 5G. Although there are several benefits to using an eSIM, such as the capacity to save numerous profiles, switching your SIM card to a different device may be rather perplexing.
Further, to address this, Google stated in February that Android would receive support for eSIM transfer with its Android 14 OS upgrade, but the South Korean giant has outperformed Google in this. In order to move eSIMs easily across devices or upgrade your existing pSIM to an eSIM, Google has been working on a method, and it’s clear that Samsung’s One UI 5.1 outdid it. This change was reported by a trustworthy tipster, Mishaal Rahman. Under settings—connections—SIM management, there is a choice to begin the conversion into an eSIM.
Wherever there are advantages, there are drawbacks too. As of now, the Galaxy S21, S22, and S23 series, the Galaxy Z Flip 3 and Z Fold 3, the Galaxy Z Flip 4 and Z Fold 4, and the Galaxy Note 20 models are eligible devices. Since there are only a small number of models, not all users can make use of this functionality. Another limitation is that to transfer eSIMs, you will need compatible Samsung devices that are both running One UI 5.1 or a more recent release. The same condition applies for the conversion of a pSIM to an eSIM.
With One UI 5.1, carrier compatibility in the US has been extended. Also, you cannot set up one eSIM only for mobile broadband and another for telephony. According to the SIM transfer support page, the South Korean technology requires a single SIM for both. Additionally, there is no accessibility for auto-data switching in the US, but as mentioned in the support information, the One UI automatically switches to the backup SIM for data if the primary eSIM is unable to connect to the network.
