What is the reputation of IIJmio's cheap smartphones? Five Benefits from Word of Mouth

I'm curious about the reputation and benefits of IIJmio's cheap smartphones!

I checked the reputation of IIJmio's cheap smartphone on SNS! From the reviews we researched, we found 5 advantages, so let's check them one by one.

Advantages of IIJmio's cheap smartphone

If you want to know the reputation and merits of IIJmio, please read on.

1.Smartphones are cheaper when purchased with a SIM.

When switching to IIJmio, you can get a discount if you purchase a smartphone at the same time as the SIM.

The discount amount depends on the device, but in the case of the cheapest smartphone, you can buy it for an amazing price of 110 yen.

On SNS, there was a word of mouth that "IIJmio has a cheap device setup price."

For reference, here is a smartphone with a discounted price of 110 yen on the official website of IIJmio.

Example of a smartphone with a price of 110 yen after applying the discount

*As of February 2022 (Click here for the latest information)

In addition, there are many models that cost less than 10,000 yen after the discount is applied.

IIJmio handles about 40 types of models, which is also a great point. If you have a particular model in mind, please apply while it is still in stock.

However, please note that terminal discounts cannot be applied unless you are transferring from another company that involves MNP transfer!

MNP transfer is a necessary procedure when you take over the phone number of your smartphone and switch to another mobile phone company.

Please note that if you get a new phone number with IIJmio, the discount will not be applied even if you purchase a smartphone at the same time.

2. Cheaper than other cheap smartphones

IIJmio plans are cheaper than other cheap smartphones.

If you have a monthly data traffic of 20GB or less, you can switch to IIJmio and use a smartphone. Prices are likely to be lower!

In addition, IIJmio is currently conducting a campaign to reduce the initial cost (usually 3,300 yen) required at the time of application to 1 yen as a benefit of joining the Giga Plan! Let's switch early before the campaign ends

IIJmio's cheap smartphone campaign list

In the case of IIJmio, the data charge is also relatively cheap at 220 yen per 1GB.

[Comparison of data charges with other companies]

< th>IIJmio< tr>
Data charge fee1GB equivalent
1GB ¥220220¥
Maineo100MB ¥55550 Yen
UQ Mobile500MB 550 Yen1,100 Yen
BIGLOBE mobile100MB ¥330¥3,300

With this data capacity Even if you run out, you can easily recharge!

In addition, there is a monthly discount of 660 yen when combined with IIJmio Hikari. If you need internet access at home, consider subscribing to IIJmio Hikari.

3. Data can be shared between plans with the Giga Plan

From June 2021, IIJmio's Giga Plan has enabled data sharing between Giga Plans. Therefore, it is recommended for those who want to share data between family members or between devices on hand.

For example, if you sign up for two SIMs with a 4 Giga plan, you can share a total of 8 GB between the two terminals.

It is also possible for one person to contract two SIMs of the 20 Giga Plan and use a total of 40 GB.

However, please note that the data sharing function can only be used with the Giga Plan line and the same mioID line.

To use the data sharing function, you need to apply for data sharing and create a share group from the member page!

In addition to the data sharing function, there is also a function to present the desired amount of data to the line with the same mioID! The present function is convenient when you want to manage the remaining amount of data individually.

4.Comfortable even during low-speed communication with the burst function

IIJmio's budget smartphones come with a convenient "burst function."

The burst function performs high-speed communication only for the first few seconds when a website or SNS application is opened.

With the burst function, you can read data quickly, so even if you run out of data and the speed limit is applied, you can enjoy the Internet comfortably with less stress.

If you choose a cheap smartphone with a burst function, you can use it comfortably without charging data!

However, there are cases where the burst function may not be fully effective when loading heavy data, such as "many large images/movies are embedded".

5.Call charges are halved when calling with a dedicated app

By using IIJmio's cheap smartphone, you can save on call charges.

In many cases, the call charge for smartphones is "22 yen per 30 seconds", but with IIJmio, if you make a call using the dedicated app "Miofone Dial", the call charge will be "11 yen per 30 seconds". Because it becomes

Furthermore, the "Family Call Discount" will be applied to calls made to terminals with the same mioID, which will be "8.8 yen per 30 seconds".

IIJmio's call charges IIJmio's flat-rate call option (unlimited calls)

If the total call time per month is 30 minutes or less, using miofone dial is more economical than adding the all-you-can-call option!

Just download the app to use Miofone Dial. It's easy to use because you can keep your phone number and sound quality and sync your smartphone contacts!

Two points to note about IIJmio from word of mouth

There are various merits in switching to cheap smartphones from IIJmio!

Exactly! But according to word of mouth, IIJmio has two caveats, so let's check in advance

Points to note about IIJmio from word of mouth

Let's switch to IIJmio after understanding two points!

1. There are times when the communication speed is slow

The communication speed of IIJmio's cheap smartphones may be slow during lunchtime when the line is busy.

I compared the communication speed of IIJmio and UQ mobile to see if the word of mouth is true.

[Transmission speed comparison between IIJmio and UQ mobile]

UQ Mobile17.4Mbps13.4Mbps14Mbps

*As of February 2022. by https://keisoku.io/mobile/

Is there a guideline for how much communication speed is necessary when using a smartphone?

[2022 latest] IIJmio (Mio IIJmio has a good reputation?Thorough explanation of merits and cautions!

For your reference, the following table shows a guideline for comfortable communication speeds.

[Reference for comfortable communication speed]

Sending and receiving email messages~1Mbps
Browsing the Internet 1-10Mbps
Watching videos5-20Mbps

Videos Other than viewing, there are many cases where communication speeds of about 5 Mbps can be used without problems.

It is recommended that you avoid watching videos during busy times!

If you want a cheap smartphone with fast communication speed, consider Ymobile or UQ mobile

If speed is important, "Ymobile" or "UQ mobile" is recommended

2. Face-to-face support is not supported

IIJmio's cheap smartphones do not support face-to-face support at stores. Therefore, when you want to solve the problem quickly and reliably, you may be in trouble.

By the way, IIJmio's support contact is as follows!

IIJmio's support window

However, there are also reviews saying that "IIJmio's support is solid."

If you can operate your smartphone by yourself, there is no need to worry too much.

If you want face-to-face support at a store, we recommend cheap smartphones with physical stores nationwide, such as Ymobile and UQ Mobile.

For those who want to enjoy the online environment with a cheap smartphone with fast communication speed, we recommend "Ymobile" or "UQ mobile".

The communication speed of Ymobile and UQ mobile tends to be stable and fast among cheap smartphones.

According to https://keisoku.io/mobile/, the communication speed of the daytime measurement on July 29th exceeded 10 Mbps. With this speed, you should be able to enjoy watching videos and browsing heavy web pages without stress.

It is a good idea to decide whether to choose Ymobile or UQ mobile depending on whether there are terminals to be contracted together.

If you use the same cheap smartphone company as a family, Ymobile is a good deal because you can get a discount.

If you subscribe to more than 2 lines, Ymobile will be cheaper!

In addition, the fact that both Ymobile and UQmobile can receive face-to-face support at stores is also a great strength.

For those who are switching to a cheap smartphone for the first time, there are many things they do not understand and their anxiety tends to grow. If you choose Y!mobile or UQ mobile, you can rest assured that you will receive solid support for any unclear points.
