"SIM Free iPhone + Prepaid SIM" or "Global Data MiFi"? (Continued) My recent guidebook situation

Now, I’m going to write about the “packet cost” and “SIM free phone and iPhone” that I announced in my last article.

To make the conclusion clear, as the title of this article suggests.

“SIMフリーiPhone+プリペイドSIM”　それとも　”グローバルデータMiFi”？

I would like to focus on whether it is better to

So, I’ve come to a conclusion.

「年2、3回の旅行であれば”グローバルデータMiFi“のほうがよい」

is.

I would like to discuss the basis for this conclusion below.

In addition, as I always say, my travel is mainly in Europe, so I’m going to talk about my travel in Europe, especially in France.

How to get a SIM free iPhone and the price

The following site summarizes well about this.

I haven’t actually tried it, so I don’t know how far it will go at this point, but in any case, unless you go to Hong Kong or Thailand, it will probably cost you about 70,000 yen to buy it.

In the following, for the purpose of various comparative studies, the

SIMフリーiPhone購入費用は7万円

I would like to proceed with the discussion on the premise that

How to get a prepaid SIM and how much it costs

Of course it varies from country to country, but in the case of France, where I often go these days, it seems to be like this.

The price varies, but roughly speaking, you can use it for a month for around 2,000 yen per trip.

It could be cheaper in other countries or with some ingenuity, but for now, just for comparison’s sake

プリペイドSIM1回の旅行当たりの費用は2,000円

I will proceed on the assumption that

In addition, I am afraid that I am quoting another person’s blog, but as far as a Google search is concerned, I will introduce this person’s blog because it is very helpful.

Amortization period of SIM free iPhone

According to the recent trend, a new model of iPhone is released approximately every year. Many people may buy a new model every two years, although Softbank’s price system and campaign may have an influence.

So, I converted my earlier assumption “buy a SIM free iPhone for 70,000 yen” into a cost per year. That is

SIMフリーiPhoneの1年あたりの費用は35,000円

The discussion will proceed as follows.

MiFi Rental

Now for the case of not using a SIM free iPhone.

以前自分のblog記事でも紹介しましたこちらのレンタルプラン利用のケースを考えてみましょう。

We’ll assume a 10-day rental per trip, plus an initial fee to cover

MiFiレンタルの旅行1回あたりの費用は初期手数料525円+1,580円×10日

The discussion is based on the assumption that

Comparison of both plans

Now that you’re finally ready, let’s compare and contrast both plans.

Just to be clear, let’s review the various assumptions.

• SIMフリーiPhoneの1年あたりの費用は35,000円
• プリペイドSIM1回の旅行当たりの費用は2,000円
• MiFiレンタルの旅行1回あたりの費用は初期手数料525円+1,580円×10日

Based on the above assumptions, here is a comparison of the cost per trip per year.

表1：”SIMフリーiPhone+プリペイドSIM”と”グローバルデータMiFi”費用比較

Number of times to go abroad	SIM-free iPhone per year + prepaid SIM ($2,000 per trip)	Global Data MiFi (1,580 yen per day, 10-day rental)
one time	37,000 yen	16,325 yen
twice	39,000 yen	32,650 yen
three times	41,000 yen	48,975 yen
Four times.	43,000 yen	65,300 yen
Five times.	45,000 yen	81,625 yen
Six times.	47,000 yen	97,950 yen

As you can see, “the size of the cost of both is switched around the second or third time”.

What this tells us is that

「年間2回以下の旅行であれば、MiFiレンタルのほうがお得」

That’s what I mean.

If you go 3 times, you can say that it’s the difference. According to this simple comparison, the SIM free iPhone plan is more economical, but considering the hassle of getting a SIM free iPhone in the first place and actually buying and setting up a prepaid SIM locally, it’s not clear whether it’s better to save around 8,000 yen.

At least if it’s me, I think it’s more economical to pay the extra 8,000 yen than to spend the time to get it and set it up.

One more analysis. Now let’s simply look at the cost of renting a MiFi for each day of your stay.

表2：滞在日数ごとのMiFiレンタル費用

Number of days to stay abroad	Global Data MiFi (1,580 yen per day)
ten days	15,800 yen
fifteen days	23,700 yen
twenty days	31,600 yen
twenty-fifth day of the month	39,500 yen
thirty days	47,400 yen

The cost of a SIM free iPhone + prepaid SIM is around 40,000 yen, so if you compare it to a simple stay of

「海外に滞在する日数が合計25日以下であれば、MiFiレンタルのほうがお得」

I think you’ll find that this is the case.

So, for me, who stays only twice a year and for 20-25 days, the MiFi rental is much more economical.

Advantages of MiFi rental: signal conditions (from real experience in France)

We think the MiFi plan is actually a better value for the signal.

This is just an actual experience, or a comparison with softbank’s packet flat-rate carrier (SFR) in France, but especially in the countryside, the signal available in MiFi rental is clearly better than that of a single carrier.

You can also save yourself the trouble of buying a prepaid SIM every time you change countries.

Benefits of MiFi Rental: MiFi can be used for more than just iPhones

It is not only for iPhone but also for PC. Whether or not you take your PC with you on a trip is up to you, but at least for me, I think I absolutely need my PC, so I think MiFi is indispensable.

Why don’t you just use a SIM free iPhone in Japan?

There may be some objections to the above. I think this is as you say. After all, even if you rent a MiFi, you are buying a SIM locked version of the iPhone in Japan anyway.

However, as long as you are living in Japan, a normal iPhone with SIM lock is enough and the cost is cheap.

This analysis was based on the premise of “buying a new SIM free iPhone for travel purposes”, but for most iPhone users, unless you are a frequent traveler, it is probably more natural to buy an iPhone and live in Japan and go abroad once or twice a year in your spare time. I think it’s more natural.

Conclusion: I will continue to rent MiFi

From the above, it was found that MiFi rental is more advantageous, including the cost, for a trip of about twice a year at most, because it is easy to apply rather than taking the trouble.

So, I think I will continue to use Global Data’s MiFi rental service.

In addition, this analysis is done from the point of view of whether it is profitable for me, so I do not think it is a general conclusion. I hope you will think that there is an analysis from this point of view.

P.S.

This is the book that I introduced last time. My thoughts on prepaid SIMs and the like are slightly different because the environment has changed so much since it was written, but overall it’s very helpful and I recommend it again.
