CrossedSignals Posted December 22, 2017 Share Posted December 22, 2017 I just returned from a business trip to Japan and have some interesting things to report regarding Sprint international roaming on SoftBank. I'm a BYOD customer (aka 1 year free) and therefore my expectations were that I would receive throttled (2G speed data) with the option to purchase 'high speed' data on a daily or weekly basis as needed. On landing and turning on my phone, I received the usual SMS messages welcoming me to Japan and noting rates for calls and texts. However, I also received a message "High-speed data included at no additional cost on this trip!" Hmm... exciting. My trip kept me in downtown Tokyo with a diversion to Yokohama for lunch one day. I definitely did not venture outside urban areas and therefore my experience is not representative as a testimony for the network throughout Japan. In both cities I can attest the network is very dense and I don't recall having a low signal situation anywhere. I was able to use the service just as I use Sprint in the U.S. On my iPhone 6, the hotspot worked great and the speeds were excellent. Towards the end of my trip, I did some speedtests (photos attached) at my hotel and at Haneda airport, connecting to Band 1 and 3. I never did see an instance where I connected to band 41 (but then again I don't have the benefit of SCP and wasn't running around with the field test mode going all the time). I was surprised at the ping times and played around with the servers on speedtest to try and see if there were any changes (nothing) and as you can see whether it was band 1 or 3, downtown Tokyo or the airport, pings were consistently in the ~300ms range (by way of reference the hotel wifi was ~4ms (assume fiber)). Overall it was impressive and considering the usual cost of roaming, the experience was excellent. 2 Quote Link to comment Share on other sites More sharing options...
CrossedSignals Posted December 22, 2017 Author Share Posted December 22, 2017 (edited) I have the speedtest screen shots but am not able to upload due to size. To save you the agony of knowing the speeds: Test 1: Tokyo 6:16am: Ping 347ms; DL 18.2Mbps UL 18.31Mbps Test 2: 8:54am Haneda Airport: Ping 358ms; DL: 48.05Mbps; UL: 24.01Mbps Test 3: 5:48AM Tokyo: Ping: 328; DL29.35; UL19.32 Edited December 22, 2017 by CrossedSignals 2 Quote Link to comment Share on other sites More sharing options...

T-Mobile does the same thing, even if you high speed data you end up with a high ping because it goes through the US. That's in advantage in places like China that have censorship because it means you can access sites that are normally blocked.

burnout8488 Posted December 22, 2017 Share Posted December 22, 2017 Very cool. Anyone think of an explanation for the free LTE data? Were you planning on buying the high speed pass had it not been included anyway? Quote Link to comment Share on other sites More sharing options...
squigey Posted December 22, 2017 Share Posted December 22, 2017 The week before Thanksgiving, I was in Osaka for work and received that same text about free high speed data when I was there. I was expecting to have to pay for the week pass for LTE. Service was solid around Osaka and Kyoto as well. 1 Quote Link to comment Share on other sites More sharing options...

I forgot about the fact that the connection is a quasi VPN back to Sprint and therefore pings suffer.

Were you planning on buying the high speed pass had it not been included anyway? I would have purchased the high speed data as my company would have reimbursed me for the charge. I do think that with AT&T and VZW doing the $10/day to use home rate plan undercuts the value of the $5/day or $25/week offerings from Sprint (and I think T-Mo). As it was, I used about 850Mb of data (mainly for the speed tests) while I was there. The other nice service was Wi-fi calling. I was on a boatload of conference calls back to the U.S. and as of today I had one minute ($.20) of international calling. That was probably more valuable than the high speed data in my case.

mnjeepmale Posted December 28, 2017 Share Posted December 28, 2017 This is helpful information. I am traveling overseas to Asia in summer next year and have a 1 day layover in Japan. Will probably see our Tokyo office while i'm there. Does Sprint charge you for calls and texts but data is free up to 1Gig? Quote Link to comment Share on other sites More sharing options...

Does Sprint charge you for calls and texts but data is free up to 1Gig? Calls are $ .20/min (free on wifi), texts are free and as far as I know there isn't a limitation on data. It's somewhat confusing given the $5/Month Japan roaming option. It would appear that the roaming option would net you free voice calls and not sure what else.

trojanman05 Posted January 7, 2018 Share Posted January 7, 2018 I was in the Nagoya area between Christmas and New Year's with my Project Fi Pixel 2 XL. Stayed connected to Softbank LTE the entire time, and to multiple bands (I remember seeing 1, 8 and 41 on SignalCheck Pro) while in Nagoya, Kyoto for a half day, and Tokyo to catch my flight back to the states. This includes solid connection underground and in the subways. Never did a speedtest, but whenever I needed to use the phone, speeds were excellent. Signal was also great on the Shinkansen (bullet train) between Nagoya and Kyoto and Nagoya and Tokyo. My work iPhone (AT&T) roamed on either AU (KDDI) or Docomo, and also stayed on LTE the entire time. And again, solid connection underground, in subways, and on the Shinkansen. Back when I was in Japan in September, I had a Nexus 6p (also on Project Fi), and that phone varied connection between Softbank and Docomo. If I remember correctly back then, my phone was connected more to Docomo than Softbank. Overall, great network infrastructure in Japan. I've been on Project Fi since October 2015 (switched from Sprint), and it's so nice traveling overseas with no extra charge for high speed data (and I've been to many overseas locations in both Asia and Europe since switching). 2 Quote Link to comment Share on other sites More sharing options...
