The Problem
International travelers waste hours researching eSIM providers, carrier roaming passes, and local SIM options before every trip. Pricing varies wildly by destination, duration, and data needs, making it nearly impossible to compare options apples-to-apples. Many end up overpaying for roaming or buying the wrong plan for their itinerary.

GigSky eSIM in Spain Review
Hi everyone, I thought I'd share my experience using the GigSky eSIM during a recent trip to Spain. During my trip planning I did not find much information about it. **TLDR below.** **Trip Length** * 12 days * Barcelona 4 days → Valencia 5 days → Barcelona 3 days **Total Data Usage** * 2.996 GB * Majority of this was used to navigate Google Maps, Spanish/Catalan translation apps, looking up restaurants, and occasionally browse reddit/web search **Why GigSky** * I have a few Visa cards that provided various 1 or 3gb data plans with Gig Sky for free as a card perk. * I ended up installing the GigSky app on my phone and activating three data plans with three different cards for a total of 7GB of free data (1gb Visa signature plan and two 3gb Visa infinite plans) **Coverage** * Overall very good. There were seldom places I did not have coverage (mainly deep inside a concrete building or in a basement) but otherwise out and about I had consistent coverage and fast internet browsing speeds that did not hinder my searches or Google navigation * My family used separate paid Ubigi plans and the coverage with Ubigi was comparable and good as well **Would I Use GigSky Again** * Yes, if it continues to be free. I am frugal and whatever is the cheapest plan works for me. Despite this, GigSky provided really great coverage for what I needed in Spain. **How Much Data Do You Need?** * Again, I mainly used my data to navigate around the cities and occasionally look things up. I did find myself browsing Reddit and other social media apps but it was not consistent. 3gb was plenty for me. * I used up \~900mb of the 1gb plan before switching to one of the 3gb plans. I used \~2gb of this plan and haven't even activated my other 3gb plan from another Visa infinite card. I have 365 days to utilize this plan if I travel internationally within this timeframe. * My BIL was consistently streaming YouTube and social media during the 12 day vacation and he ended up using 11gb of his 25gb Ubigi plan. **TLDR:** I used a total of 3gb of a free GigSky eSIM data plan for a 12 day international trip to Spain. The coverage was excellent. I used it to navigate the city via Google Maps. You could probably get away with 15gb in the same timeframe if you are a heavy social media user. I would use GigSky again if it was free, otherwise I would choose the cheapest eSIM plan available (GigSky, Ubigi, Airalo, etc.)

eSIM with smart routing for global app compatibility
Been thinking about a problem travelers run into but don’t always realize upfront. Most people assume that once they have data abroad, everything just works. But in reality, app performance can vary depending on how the connection is routed, not just the signal or speed For example, in some regions, certain apps behave differently if traffic is routed through specific locations. So even with full bars, users can still run into limitations. A potential solution could be an eSIM platform that gives users control over routing, like choosing different IP regions, so they can optimize for app compatibility depending on where they are. I’ve seen something along these lines with platforms like **Nubes eSIM** offering options such as non-HK IP routing, which seems like a step in that direction. Feels like there’s room to expand this into a more user-friendly product, maybe with automatic switching based on app usage or location.

I've found a way to get free unlimited data eSIMs but they last only 24h. Is there an efficient way to manage this?
I'm wondering what I could do to manage having access to a virtually unlimited numbers of eSIMs. These offer unlimited data for 24h each. The problem is that these cards have to be swapped out every day because the previous one stops working. On android it's possible to do manually but the process takes 5 or so minutes and sometimes is buggy when done manually. You then even need to turn on roaming and set that new eSIM for data. I was wondering if there's an app that can put enabling the new eSIM every day on a schedule and potentially even fix the settings by enabling its roaming and setting it as the preferred data SIM. This way I could replace my provider in a more seamless way. Any ideas?
