Important Information

IMPORTANT: Be cautious of providers advertising "Unlimited Data" without clearly disclosing their limits. Vague wording about slowdowns "beyond their control" that "normalize the next day" usually points to a hidden daily cap — always check directly or review their website for details. Our eSIM includes a clear 3GB daily high-speed data limit. Once reached, speeds reduce to 128kbps for the rest of the day. Your high-speed data refreshes every 24 hours from activation, giving you a fresh 3GB each day for the duration of your prepaid plan.
