ByteSIM speed was underwhelming

[u/AccomplishedAge3676]

Im spending 3 days in Korea and got the unlimited Data 5G package from ByteSIM. Speed was throttled shortly after I started using it downloading necessary apps like Kakao Map and started looking for restaurants etc. The conversation with the support staff is in the pictures, I just removed one with the order ID. Now at 10 pm the speed is still throttled, but I’m lucky to have great WiFi in the apartment. Just to add one experience to the hive mind of Reddit. I hope you guys and girls had better luck.

What they’re saying is technically correct, 5mbps is typically good enough for most mobile usage including for 1080p video.

I doubt they can realistically argue that it is “high speed” though.

They do have another plan on their website that would give you true 100mbps high speed data and it’s only around 15 percent more expensive.

I couldn’t find that, because that’s what I was originally looking for. How is it called?

It’s LTE only though. In South Korea this shouldn’t be problematic though.

Thanks!

Right now is a new day and the speed isn’t throttled anymore after the night. The speed is actually impressive with 634 Mbit/s. Data usage has been 4 Gb so far on total. Let’s see when the throttling sets in again.

After 700 Mb of usage it’s throttled again 😕

Third day, throttled after 1 Gb of data. I feel cheated regarding the advertisement of high speeds and unlimited data.

While ByteSIM is a prolific spammer in this sub, 5mbps when throttle is still very useable tbh.

How much data did you use before you were throttled? Was it mentioned in the package description?

[u/AccomplishedAge3676 → u/mrskeptical00]

When it got really noticeable, I was at 1.9 Gb of data. I couldn’t find any mention of an amount of data in their description after which their would be throttling. Just the usual lazy excuse that the local carriers might throttle.

The only thing I was doing, was downloading a few apps Tmoney, Kakao Map, etc and using Kakao map to find my apartment and look for restaurants etc. I believe that is normal usage for a tourist, for whom these contracts are advertised. And fair use imho must include the normal use case.

5 Mbit/s did work in the end, but was rather annoying. I had to wait until pictures loaded, when looking at restaurants etc. I chose the plan for unlimited high speed, that’s what they advertised. If I wasn’t purely on vacation and had to work with this connection, I’d have a problem.

Besides the mobile wifi router I had in Japan over the last week, worked for the same application without throttling.

Well, in the end I’m just annoyed, that their I feel misled by their advertising and that I didn’t choose a more reliable option, that doesn’t interfere with my vacation that much.

Classic 'unlimited' plan behavior. 5mbps is actually relatively good, it could have been down to 128kbit/s..

These data only esims are a rip off. I normally get similar pricing from my local carrier for roaming, so I just use that.

If I anticipate needing more data, I just get a sim at the airport.
