The reason why it is more comfortable to choose a cheap SIM that sets donedone or maximum speed to "slow".MVNO is balanced than speed!

Do you have the Internet on your smartphone and the operation is extremely slow depending on the time of day?Although there is a possibility that the memory may be insufficient, most of the causes are that the communication speed is slow.

General cheap SIMs (MVNOs) rent "bandwidth" and "line" from telecommunications carriers to provide services to users.There is no need to set or manage base stations, and the procedure is basically online, so the running cost is the minimum.The basic fee will be cheaper accordingly.

However, MVNO's difficulty is that the amount of data that can be communicated at a time is small compared to communication carriers, and it is likely that the speed will be reduced during the daytime when the number of users increases at a stretch, and the speed is likely to decrease during the daytime.

However, there are some MVNO services that emphasize stability by reducing the communication speed to "3Mbps", such as "Donedone (Basic U Plan: au Line)" provided by Big Lobe Co., Ltd.

By referring to the company's public communication speed measurement results, it can be seen that the speed of "3Mbps" is maintained 24 hours a day on weekdays and holidays.

The data capacity of Donedone (basic U plan) is "50GB" per month.Even after exceeding 50GB, communication is possible at the speed of viewing the maximum "1Mbps".With this, the monthly fee "2,728 yen (tax included)" is quite advantageous.

If you refer to the "recommended sustainable speed" released by YouTube, you can watch videos stably with a high resolution of "HD 720P" if 3Mbps is out.

If it is the screen size of the smartphone, the resolution is sufficient for the "SD 480P", but the tablet size makes the roughness conspicuous.However, there is no problem if it is HD 720P.

Donedone is compatible with tethering, so you can use a smartphone with a Wi-Fi router.Even if you have a SIM card slot, such as Fire HD 8 or iPad mini 6 (Wi-Fi model), you can enjoy Prime Video and Netflix on the go.

Reference: LINE Mobile

The data capacity that can be used on the month at the speed of 3Mbps is "50GB".If you refer to LINE Mobile data, you can watch videos at a high resolution of HD 720p of about 50 hours.It can be said that it is enough for those who use optical lines at home or watch videos on smartphones.

Maximum "1.Mineo's excellent option "Packet unlimited Plus" is limited to 5Mbps and can communicate at a stable speed like Donedone.I actually use the service, but maintain the maximum speed even at noon.

Measure mineo's communication speed at 12:42 pm

1.Because it is 5Mbps, it is difficult to watch the video stably at the HD 720p resolution.Therefore, it is not recommended if the use of a tablet is assumed.However, there is no problem with video playback with SD 480p resolution.This is enough for smartphones specialized.

"Packet all -you -can -PLUS" is based on "unlimited packet", as the name implies, and basically all -you -can -communicate data communication.It is stipulated that "if you exceed 10GB of data communication in 3 days, the speed may be limited," but still the minimum "100GB", which is twice that of Donedone, can be used.

From mineo

The charm of mineo is that the communication cost is low.If you combine a single type (1GB) that is dedicated to data communication and the unlimited packet Plus, the monthly fee is "1,265 yen (tax included)".The dual type for voice calls is a plus of 10GB (1,958 yen per month) or more.Exceptionally cheap considering the high degree of freedom!

If you go to school or work, the time to use your smartphone is roughly limited.In other words, it is meaningless if you can not use it to some extent during that time.

donedoneとmineoはMaximum "100Mbps』で通信する事は出来ません。しかし混雑時でも安定した速度を維持出来るのは最大速度を遅めに設定しているからこそ。MVNOは『最大速度遅め』なサービスこそが実は狙い目。SIM選びで失敗した事のある人は是非お試しください。
