How we tested: devices, protocol, and scoring
We evaluated 5 eSIM providers for Sydney using a standardized testing protocol over 14 days in Q2 2026. The composite score weights four dimensions: Measured Speed (30%), Activation Pass Rate (30%), Support Response (20%), and Price Accuracy (20%). Speed measurements used Ookla Speedtest, run 3 times daily at 09:00, 14:00, and 20:00 local time on each of 4 devices: iPhone 15 Pro Max (iOS 18.4), iPhone 16 Pro (iOS 18.5), Samsung Galaxy S24 Ultra (One UI 6.1 / Android 14), and Google Pixel 9 Pro (Android 15). Measured Speed accounts for 30% of the composite. Activation testing followed a binary pass/fail protocol. Each provider was installed fresh on all 4 devices. A pass required active data within 5 minutes of QR code scan. Time to first byte was recorded for each attempt. Activation Pass Rate accounts for 30% of the composite. Support response times were measured across 5 standardized queries per provider: activation failure, data balance discrepancy, refund request, APN configuration, and plan upgrade. Each query was submitted during business hours and off-hours to capture full-cycle performance. Support Response accounts for 20% of the composite. All plans were purchased at full retail price. No press accounts, review copies, or sponsored access was used. Prices were verified against each provider's checkout page on the Monday before publication. Price Accuracy accounts for 20% of the composite and reflects discrepancies between advertised and checkout totals.
