02 (Two lines...is that still possible?): Aru-san's daily blog > 자유게시판

I'll write about a small topic 2022/02/02 (Two lines... you can still do that, right?)

I thought it was more advanced, but it seems that it's not that advanced in reality. When it starts, it's going to be a big mess on the ground lol

For now, au will be getting lines wholesaled from SB, and it looks like it will be a few hundred yen a month + toppings. Not only eSIMs, but physical SIMs will also be prepared.

However, if there is a communication failure, the ideal situation would be to be able to roam to another company when you want to make a call with the phone number of the carrier where the communication failure is occurring, and even if the communication is guaranteed, the call will not be guaranteed. Of course, if you can make calls at that level and things can be resolved, that's the best thing, but from the user's perspective, if you can't use the SIM you have without any discomfort, it can be said that there is not much value in using it.

At least, from the perspective of the person who manages the company's mobile phones, it's just an increase in numbers and there's no benefit. Oh, Slack or Teams are fine. So that's what the data SIM is supposed to be secured with. Hmm.

For example, can you connect an SB line to an au APN? Well, as it says SB wholesale, the APN will be dedicated to SB lines, but can SB do that? That's the only question I can ask. As I wrote yesterday, I think it's time to standardize SIMs.

The barrier to overcome is to have multi-SIM devices that cover the platinum bands, even for entry-level devices. If devices with two SIM slots or SIM + eSIM are not mandatory, there could be a series of models that are not compatible with the service. How far can this be done?

In addition, if the configuration profile is the same on an iPhone and it supports multiple carriers (for example, au SIM + Docomo eSIM on IIJmio, SB SIM + au eSIM on mineo), the data line can be switched to a line that can be connected without any problems. IIJmio has actually set up and operated the combinations written in the test, so I don't think there is much reason for carriers to start doing that. Now may be the time to make a move on multi-carrier MVNOs lol

In conclusion, it's enough for each company to create something like povo and buy packet capacity as needed. Although ahamo and LINEMO are positive about crushing other companies and increasing profits, systems like povo are stagnant. Furthermore, povo also requires charging once every six months. It would be best if it could be quickly charged during communication failures.

I'm sorry to talk about povo, but the 90-day 3GB for 1,480 yen is very convenient, so I would like it to be permanent. It suits my usage, and it's so comfortable that I would even like to use it on multiple devices. It's a quality that is typical of a sub-brand run by the original company. I don't want Docomo or SB to go as far as prepaid SIMs, but I think it would be good if they started a service similar to that. Well, Docomo probably can't do that due to their relationship with MVNOs.

The end

Well, if you set povo as a secondary SIM, either eSIM or physical SIM, you can top it up right away.
