eSIM.io Europe Package Has Poor Internet Performance in Spain

I purchased the 20 GB Europe eSIM package from eSIM.io and have been using it in Spain for the past three days. I paid $16 USD for this package, but I am extremely disappointed with the quality of the service. Having previously used several other eSIM providers, I find eSIM.io's performance to be significantly below expectations.

While traveling, reliable internet access is essential. However, I frequently cannot load maps, open Google, or even perform basic online tasks. The connection often hangs without transferring any data, making the service unreliable. I have experienced this problem several times a day over the past three days, and the connection has not been stable or dependable.

I have already tried basic troubleshooting steps, including restarting my phone and turning Airplane Mode on and off, but the issue persists. I also contacted your support team through the application a short while ago. Nevertheless, I want this complaint to remain open because the seriousness of the poor performance has not yet been resolved.

I respectfully request that the service I paid for function properly throughout Europe, particularly for essential services such as maps and basic internet access. If the connection problem cannot be resolved promptly, I request a reasonable remedy, including a refund or appropriate compensation for the poor quality of service I have received.
