With the launch of povo2.0 5G SA, connection failures and SIM-free Android users report being out of service area one after another.

The online-only brand "povo2.0" will start "5G SA" from August 25, 2026. However, a number of users who tried to open the service using SIM-free Android devices reported that they were unable to use the service because they were out of range.The other line on their dual-SIM smartphones was also out of range.

KDDI released an explanation on August 28th, saying, ``It was discovered that the connection settings had been unintentionally incorrect.The settings were changed on the 27th (night), and devices that support 5G SA can now connect to the network.''

There was speculation on social media that the site may have been set to deny access from unsupported smartphones.

I don't know if it was an "unintentional misconfiguration", but it's true that carriers don't want to accept connections from all kinds of devices.

It is no wonder that the idea is that only verified devices will be allowed access.

However, open market smartphones such as povo are so popular that they can be contracted freely and easily.

Despite the appeal of an unprecedentedly open stance, it is a rather unreasonable idea to assume that connection will be possible with a smartphone sold by au.

As a carrier with a lot of strength, I think they should have tested the mainstream smartphones on the market as much as possible and added compatible models to their lineup.

However, recently, problems such as ``Log-in and authentication from minor apps are not completed on some Android devices'' and ``Some text cannot be read when starting an app on Pixel 11 Pro Fold'' have been seen here and there on X.

There was also an issue with certain games appearing pink on the Pixel 11 Pro.

There are so many Android models around here that operation verification has not kept up with them at all, and in the first place, operation verification has not been performed on many Android smartphones.

It would be ideal for carriers and app developers to increase the number of devices that need to be tested, but this would naturally lead to higher costs, and users would have to bear the cost.

It's great that Android for the open market is becoming more popular, but at the same time, there is no doubt that the burden on users who are worried about things not working properly is increasing.
