Without SIM Cards:

No one wants a mobile phone without a SIM cards. Without one, a mobile phone feels more like a toy. The SIM card, or Subscriber Identity Module, is crucial for identifying subscribers to network service providers. In the early 1990s, with the expansion of GSM technology, a Without SIM Card was as essential as a bank credit card today. The evolution of SIM technology has been rapid: the mini SIM was introduced in 1996, followed by the micro SIM in 2003, the Nano SIM in 2012, and now we have the e-SIM, or embedded SIM.

Due to technological advancements, the landscape of mobile connectivity is changing quickly. Like many other countries, Bangladesh is entering the era of e-SIM. Without SIM Cards-Grameenphone is set to launch its e-Without SIM Cards service soon, sparking curiosity and questions among users. The e-SIM works with mobile phone software, allowing for a virtual SIM to be programmed into the phone’s motherboard chipset.

Installation is straightforward: users can activate an e-SIM by scanning a QR code provided by their operator and following their instructions. When the internet data pack is activated, a configuration SMS from the operator automatically sets up the internet profile on the device.

Each technology (Without SIM Cards) has its pros and cons, and e-SIM is no exception. One major advantage is that, since the e-SIM is software-based, there’s no need to physically insert a SIM card.

There’s no risk of losing or damaging a physical SIM, and e-SIMs are particularly convenient for IoT devices. They also tend to offer better battery life due to smaller circuit sizes that consume less power.

However, there are drawbacks. If a mobile phone is damaged or won’t turn on, the e-SIM cannot be used in another device. Recovering SIM numbers and SMS is challenging unless cloud backup is enabled. If the phone needs resetting, the e-SIM configuration must be reestablished. Switching networks can also be cumbersome, and there is a potential risk of hacking.

Without SIM Cards: India has successfully implemented e-SIM services for several years, but there have been incidents of e-SIM hacking through social engineering techniques. Despite these risks, the advantages of e-SIM technology outweigh the disadvantages. Change is inevitable as technology progresses. Currently, e-SIM support is primarily found in high-end phones like various versions of the iPhone, Google Pixel, Galaxy S series, and Motorola devices. However, we can hope that this feature will soon be available in more budget-friendly phones.
