Slow Data Speed
Common causes of slow speeds and how to improve performance.
Slow Data Speed
If your eSIM is connected but the internet feels slow, here are the most common causes and solutions.
Common Causes
Network Congestion
In busy tourist areas, airports, and city centers, mobile networks can become congested, especially during peak hours. Try again during off-peak times or move to a less crowded area.
Weak Signal
If you are indoors, underground, or in a rural area, the signal may be weak. Move to an area with better coverage — near a window or outdoors usually helps.
Data Limit Reached
If you have used all your data allowance, the connection may be throttled or cut off entirely. Check your remaining data in your Simsima account.
Wrong Network
Your device might have connected to a slower network. Try manually selecting a different network operator:
Quick Fixes
Speed Expectations
Speeds depend on local network infrastructure, congestion, and your device capabilities.
If Speed Is Consistently Poor
