SIM Trivias

SIM Basics

“SIM” is the capital letters of Subscriber Identity Module, which is known as SIM card. SIM card, a kind of IC card, is inserted into mobile devices such as smartphones to enable users to do voice talk and have internet access.

Limitations of
SIM card

If you want to use your own mobile device even overseas, there are some ways as follows.
①Obtain a local SIM card
②Use international roaming service that your contracted MNO offers
③Get into a rider for overseas use from your contracted MNO
④Rent a pocket Wi-Fi with local SIM
In case you use a local SIM card, you need to get your device SIM unlocked and may have to manually change access point network (APN) at a destination. You know how expensive it is to use international roaming services. Overseas use rider, of course, requires you to pay more in your subscription and there may be countries or regions where you can not use your device.
When you rent a pocket Wi-Fi, you can get your multiple devices including a note PC connected at the same time but it is a hassle to book a rent, pick it up and drop it off. Also you always need to carry it with you as an extra.

eSIM will create a new eco-system in mobile communication

eSIM can be described in simple wordings such as “A new mobile communication technology that needs no physical SIM inside of devices.” However, this does not mean subscriber identities and authentications are no longer necessary. By replacing the roles of a physical SIM, eSIM as software in a mobile device practices identification and authentication. Wherever you are in the world, you can select and purchase an eSIM data plan among plans that your eSIM device identifies to be available at your location. All you need to do is to pay for the plan, install the plan into your device over the air and get connected. Obviously, this enables you to be freed from paying for international data roaming or for pocket Wi-Fi rental.

eSIM era has just started

Though eSIM appears to be quite innovative, it will take a bit longer for eSIM to create a new eco-system.
One of the reasons why is that eSIM can be used only with eSIM compatible mobile communication devices. Almost of all smartphones that have been in markets last few years are eSIM compatible. Nonetheless, still eSIM non-compatible smartphones manufactured in the past years are being circulated. Next reason is that, especially in Japan, mobile network operators (MNOs) are not very positive to support eSIM and few attractive data plans are available for eSIM device users. (MNOs have fair reasons why they are reluctant with promoting eSIM. This shall be discussed at another opportunity.)
Having said all these, it is certain that more and more eSIM compatible devices shall be shipped and circulated at a very rapid pace. A reality is that, while eSIM compatible devices circulate further, few data plans that work well with the devices are available.

eSIM solutions CE-Cet Associates offers

Under a frustrating situation for eSIM compatible device users to have few data options with which they best enjoy the devices, CE-Cet Associates is offering attractive eSIM solutions that can meet demands and expectations from such users by getting allied with overseas MVNOs and eSIM venders. The MVNOs and venders source data lines from MNOs over the world and bundle them into eSIM solutions for eSIM compatible device users. CE-Cet Associates provides such solutions on EC with solid understanding about technologies that the allied partners have.

Often called as “Cloud SIM”

The name, vSIM, comes from Virtual SIM as its official name, but, a wording “Virtual” may be a bit misleading sometimes. Therefore, this technology is often called, Cloud SIM, instead. From its appearance that no physical SIM is necessary and its device can be used anywhere in the world, it looks identical to eSIM. However, its technical architecture is different from that of eSIM.

By way of cloud, access to pools of physical SIM cards

From a viewpoint that vSIM is a kind of software embedded in a device, there is no big difference between vSIM and eSIM. But, while eSIM remotely (over-the-air) downloads data line profiles directly, vSIM downloads data line profiles, via cloud, from physical SIM cards pooled in so-called “SIM Bank”. In a SIM Bank, a lot of physical SIM cards over the world are pooled. More specifically, vSIM software in a device via cloud reaches necessary SIM cards (ones your purchased plan need) in a SIM Bank and mounts the profile of the SIM cards to get connected. This is why it is officially named virtual SIM.

Developed by MVNOs with cutting edge technologies

vSIM has been developed and still improved by MVNOs with the cutting edge technologies. From a fact that no manual switch-over of SIM card is needed to get connected anywhere in the world, it is fair to say vSIM was a cross-border mobile communication solution ahead of eSIM. On the other hand, while eSIM is aimed at building up a new eco-system consisting of device manufacturers, MNOs/MVNOs and users, in vSIM, the MVNOs manufacture devices and procure physical SIM cards from MNOs to pool in SIM Banks. Therefore, vSIM is a solution under the existing eco-system.

vSIM solutions CE-Cet Associates offers

One of reasons why vSIM Wi-Fi routers are widely utilized in rental markets is that stable performance of quality is available at cheap prices. The quality, stability and price competitiveness can be attributed to vSIM the architecture of an individual MVNO in which hardware and software are managed together. Normally Wi-Fi rental is priced on day-pass, but, especially for corporations with constant overseas business travelers, it is recommended devices are purchased to be held as inventory and data are purchased online on-demand basis. This is more financially justified.

CE-Cet Associates is in partnership with an MVNO with the most advanced vSIM technologies and offers vSIM hardware with flexible data plans to best meet needs from business travelers and travelers for pleasure.
