Data Allowance
Assess how much data you typically use daily for maps social media and browsing. Some plans offer unlimited high-speed data while others cap at specific gigabytes before throttling. Choose a plan that matches your usage habits to avoid unexpected slowdowns.

Validity Period
Check how long the plan lasts to ensure it covers your entire trip duration. Some options offer seven days while others provide up to thirty days of service. Match the validity to your travel itinerary to avoid lapses.
If your trip extends beyond the plan validity consider purchasing multiple plans. Ensure the start date aligns with your arrival.
Network Coverage
Different SIMs utilize different networks like AIS or others that may have varying coverage areas. Popular tourist spots usually have good coverage but remote areas may vary. Look for reviews confirming reliability in regions you plan to visit.

Device Compatibility
