Holafly

Pros

• Offers unlimited data plans in many regions, including Europe.
• Bypasses the 'Great Firewall' in China by routing data through servers in Singapore, eliminating the need for a separate VPN.
• Simple setup process that can be completed quickly via the app or airport Wi-Fi.
• Reliable performance for essential travel apps like Google Maps and WhatsApp.

Cons

• Generally more expensive than other eSIM providers like Airalo or Mobimatter.
• High latency (ping) can occur because data is often routed through different continents, causing delays in busy areas.
• Reports of speed throttling on 'unlimited' plans after heavy usage.
• Mixed reliability in China, described by some as 'hit or miss' despite the built-in VPN effect.

Caveats

• The 'unlimited' data claim may be subject to fair usage policies or throttling depending on the region.
• International data routing can cause significant lag, which may affect real-time applications.

Best for

• Travelers to China who want immediate access to blocked apps without a VPN.
• Users who prefer the peace of mind of unlimited data and are willing to pay a premium for it.
• Short-term travelers looking for a straightforward, app-based setup.

Avoid if

• You are on a strict budget and only need a small amount of data.
• You require low-latency connections for gaming or high-performance tasks.
• You are traveling to a region where local eSIMs or cheaper competitors offer better local routing.
