I originally had Sprint send me a new Sim card for free.
I replaced it and it works fine.
Just a little disappointed that the top of the screen changed from Sprint to T-mobile.

I can try contacting support ？.

Really, ？,


this new model is the Sprint version, but it is direct from the manufacturer and should work with both CDMA and GSM, but when I received it, it didn't work, in other words, I followed the on-screen instructions to move data from the old one to the new one, etc. In other words, I followed the instructions on the screen to move my data from the old one to the new one, and an error message appeared saying "Please go to your nearest Sprint/T-Mobile store to complete the process.

So today I went to my old Sprint store, but to my surprise, it was closed and there was a sign telling me to go to the T-Mobile store. I went to the T-Mobile store nearby and they set me up with all sorts of things, but they asked me to switch my account to T-Mobile. If you switch to T-Mobile, the monthly charge will be $70 instead of Sprint's $100. I thought it was not so different from Sprint, so I agreed.

I also asked what kind of service they have in Japan since I was going on a trip to Japan, and they told me the same thing as I heard from someone here on Vivi, that the data speed is slow 3G, but you can talk as much as you want. T-Mobile is a little better than Sprint because I had to pay $5/month only when I travel.

I looked up

Here are the details of T-Mobile's Simple Choice Plan for Japan:

Calls: 20c per minute in and out to any country - cheap
Texting: Unlimited, included at no extra charge
Data: Unlimited,
Must have Simple Choice Plan, which costs min $ 50/month.

So, data is slow but "unlimited" but talk costs 20 cents/minute. So I have to be careful to hang up as soon as I'm done with my business. Well, if you have a Skype/Line account, you can pay the Skype/Line fee since this is a data connection.

I have always been a Sprint user and went to Japan from June-August. About 2 weeks before I left for Japan, I switched to a T-mobile SIM, despite my concerns. When I arrived in Japan, I found that I could watch videos smoothly and without any problems with Sprint, but with T-mobile, just searching the internet was extremely slow, even navigating pages took up to a minute.

I couldn't stand the slowdown and switched back to a Sprint Sim in the third week after arriving in Japan and being able to walk around. Since I didn't know how T-mobile works in Japan, it was a good decision to bring my old SIM with me just in case. Sprint's customer service was very helpful in chatting with me about reactivating the old SIM, so I had no trouble.　The data speeds on T-mobile were slower than I expected for me and were a world apart from Sprint.

How were other T-mobile users' data speeds in Japan ？?

Muchasuro,

As you may already know, the merged Sprint (CDMA) / T-Mobile (GSM) companies will unify their cellular transmission system to T-Mobile's GSM system from next January or June. Therefore, in the future, it will be meaningless to talk about the connection with Sprint at home and abroad.

There are some English sites that talk about how T-Mobile phones connect in Japan, and they say that the talk is ok, but the data is so bad that it is useless, and you have to move to a place where Wi-Fi works. However, as mentioned above, both Japan and the rest of the world will be using the T-Mobile system, so we have no choice but to accept this.

I was told that the data speed in Japan was 3G, but the above English forum said it was 2G, which is certainly not usable. T-Mobile can't afford to remain the same as before because once this pandemic is over, tourists from the US will be flooding into Japan again. Let's hope that T-Mobile will take some kind of action.

Until then, I may rent a WiFi router that uses Docomo or AU radio waves instead of relying on my phone's data communication if I need fast data communication such as uploading to YouTube in Japan. In Tok, I will use T-Mobile phone for hotel/inn reservations, etc., as it does not seem to be so much of a problem, aside from the service area.

Yes, I understand that the Sprint SIM will not work. However, I was surprised at how slow T-mobile's data was in Japan, and I didn't know if it was because of my device, a bad setup, or because it was T-mobile.　It's a shame, because by choosing Sprint, I didn't have to rent a WIFI router in Japan, which would have been very convenient and helpful.

If anyone who travels back to Japan frequently knows of a carrier that has as good a data connection that works as Sprint has and doesn't cost extra, please let me know. Thank you in advance.

＞ If anyone knows of a carrier that offers the same good data operation and no additional cost as Sprint so far, please let me know.

Now that Sprint and T-Mobile have merged, everything in the US will be integrated into the T-Mobile system. In other words, data in Japan is not available in the U.S. In other words, data ・ speeds in Japan will remain slow. Also, AT&T and Verizon are also slow in Japan for both voice and data, and they charge for it.

So if you want high speed data in Japan, you will have to rent some kind of paid device.

Although each US cell phone carrier advertises that their cell phones "work" when travelers take them abroad, they are in effect paying a minimal fee to the carrier in that country, and as a result, the call/data capabilities in that country should be set to a minimum.

Therefore, smart travelers don't rely on the telecom company's service and find a free WiFi environment, especially in urban areas, where they can communicate as much as they want. In my case, however, I travel only in the suburbs, rural areas, and mountainous regions of Shikoku by foot, so I use my cell phone only to make reservations at lodgings. Most of the hotels are "minshuku" level private houses, which do not even have WiFi.

As I mentioned in another topic, I thought the merger between Sprint and T-Mobile was 50/50, but in reality, T-Mobile seems to have swallowed up Sprint.

I mentioned this somewhere, but when I went to a T-Mobile store and asked them to change my SIM card, they told me that if I switched my account to T-Mobile, they would give me $ 70 per month, and I thought it was a good deal, so I agreed. Today I checked my new credit card account and found that Sprint charged $ 101.11 in September and $ 70.00 from October. This amount includes my wife and I's two phones (2 Lines). Well, I guess it will go up eventually.

The service has not changed much from Sprint's time as follows.

$ 70.00 for 2 Lines

includes all applicable discounts and promotions. Taxes and fees included.

High-speed data

Unlimited 5G&4G LTE with 100GB of Premium Data,

What am I supposed to make of this? Is it unlimited up to 100GB, or is it unlimited with very slow speeds after 100GB? Well, we don't use our phone line much since we use almost 100% of our data under our home WiFi, and even when we were on Sprint, we used at most a few hundred "mega-mega" per month.


There is another topic discussing Hotspot/Tethering capacity, but our account is capped at 5GB, which we don't use at all. It is useful. However, the data speed in Japan seems to be 3G and sometimes video does not run smoothly.

Double Kim Man,
I am not asking for information on out-of-country connectivity for the SPRINT line that is being discontinued. I am posting this because I thought it might be my personal phone model, and I wanted to know how other T-mobile users and other carriers are using it in Japan.

Before Corona, I used to travel back and forth to Japan every 3 months for work, so I used to rent pocket Wi-Fi before I went with Sprint, then I bought a Japanese pocket Wi-Fi and used the data carrier of my choice.　But when you have even one more device, you have more things to charge and manage, and it gets complicated.
When I switched to Sprint, my data was crisp and unlimited and very convenient.

I don't want to have to worry about recharging my pocket wi-fi again, and I don't want to be stuck with T-mobile, which has cut back on service.
AT&How is the WIFI connection speed in Japan for T and Verizon users?

＞ I am not asking for information about your connections outside the country

Well, I am very sorry about that. I have a bad habit of blabbing to people everything I know.


＞ I wanted to know how other T-mobile users and other carriers are doing in Japan

I was with Verizon before I switched to Sprint. I brought my Verizon phone to Japan and the connection was not so good. Moreover, Verizon/AT&T charges a fee for the use of their phones in Japan. Also, I imagine that the current 3 major carriers (AT&T, Verizon, and T-Mobile) are all Softbank, whose coverage ・ and communication capabilities in Japan are a step lower than those of the other 3 carriers. And I am assuming that the data speed is still 3G. If you have a definite opinion that this is not true, please let me know here.

＞ It's a hassle to worry about charging pocket Wi-Fi and having to carry it around

That's true. However, if you are going to upload your own videos to YouTube while traveling in Japan, I think you will have to rent a paid pocket Wi-Fi. If you can get a good Wi-Fi connection at the hotel where you will be staying, that would be the best choice, but I would not recommend renting a pocket Wi-Fi.

＞ Verizon/AT&T charges a fee to use a phone in Japan


When I brought my Verizon contract phone to Japan 5 or 6 years ago,

I was charged cents per minute for calls over ? I had to pay cents per minute if the total minutes of the call exceeded 5 minutes, and for data, I had to pay for the amount of data over a certain number of megabytes.
