A 멕시코 eSIM is a prepaid digital SIM that gives an unlocked eSIM-compatible phone mobile data while traveling in 멕시코, without using a physical SIM card. After purchase, you install the eSIM on your device, choose it as your mobile data line, and connect to a supported local network when you arrive.

Your phone must support eSIM and be carrier-unlocked to use a ByteSIM 멕시코 eSIM. eSIM support can vary by phone model, carrier lock status, and the region where the device was sold. Please check the ByteSIM compatible device list before you buy.

ByteSIM eSIM delivery is digital and usually immediate after payment. Your eSIM QR code and setup details are sent by email and can also be accessed in the ByteSIM App, usually within a few minutes. No physical SIM card is shipped.

Install your 멕시코 eSIM before your trip while connected to stable Wi-Fi, then turn it on when you are ready to use mobile data. You can scan the QR code or install through the ByteSIM App. Most plans start when the eSIM first connects to a supported network at your destination.

Most ByteSIM plans start when the eSIM first connects to a supported network at the destination, not when you buy or install it. Some plans may start on a selected date or require activation through the ByteSIM App. Always check the activation note shown in the plan details.

All ByteSIM plans include unlimited data, and most plans support high-speed 5G where available. Check the plan’s Network or Speed field before purchase: if it shows “Speed: 5G/4G/LTE”, the plan supports 5G; if it shows “Speed: 4G/LTE”, 5G is not included. Daily and total-data plans continue at unlimited 128kbps after high-speed data is used. Truly unlimited plans shown as “Unlimited Data (*5G Network)” or “Unlimited Data” guarantee smooth 1080p HD streaming speeds, even under Fair Usage Policy. Actual speed depends on local coverage, device support, and network conditions.

On daily and total-data plans, your connection continues at unlimited 128kbps after high-speed data is used. This is a 2G-like backup speed designed to keep you reachable, not a normal browsing speed. It is mainly useful for text messages, simple notifications, and contacting ByteSIM support if needed. Web browsing, maps loading, social media, video calls, app downloads and streaming may feel noticeably laggy or may not load smoothly.

Calls and texts are available only on ByteSIM voice plans. Data-only plans do not include traditional phone calls or SMS, but you can still use apps such as WhatsApp, iMessage, Telegram, FaceTime, Google Maps, Uber and email over mobile data.

Yes. Your WhatsApp number stays the same when you use ByteSIM for mobile data. WhatsApp, iMessage and other apps remain linked to your existing phone number. On a dual-SIM phone, you can keep your primary SIM active and use ByteSIM as your travel data line.

Yes. All ByteSIM plans support hotspot and tethering. You can share your mobile data with a laptop, tablet, or another phone. Hotspot performance depends on your device, local coverage, network conditions, and how many devices are connected at the same time.

You can manage your eSIMs and access all purchased data plans by logging into the ByteSIM App. The app lets you view your purchased plans, check plan details, and manage your travel eSIMs in one place. Some plans may support renewal or top-up, while others require purchasing a new plan after the current plan is used or expires.

If you lose your QR code, log in to the ByteSIM App or check your order email to access your purchased eSIM details. If you delete an installed eSIM from your device, contact ByteSIM support before trying to reinstall it. Some eSIM profiles can only be installed once and may require support review or replacement.

ByteSIM offers a 180-day refund guarantee for eligible orders, subject to the Refund Policy. If your eSIM cannot be used due to a verified service issue, contact 24/7 support for troubleshooting, replacement, or refund review. Refund eligibility depends on the order status, plan usage, destination, and policy conditions. See the ByteSIM Refund Policy for details.
