What is an eSIM and how do I install it?
An eSIM is a digital SIM profile. Most supported devices install it by scanning a QR code, adding the plan in settings, and enabling it when needed.
Help resources for installation, compatibility, activation, and eSIM troubleshooting
A practical help centre for onboarding and everyday eSIM questions
Use this page when you need quick answers about setup, supported devices, QR activation, data usage, or common eSIM issues.
What You Can Resolve Here
A help page focused on onboarding and support
The goal is to reduce friction before activation or after purchase by grouping common setup and usage questions in one place.
Check whether a phone supports eSIM and whether it is carrier unlocked.
Understand QR installation, activation timing, and data-only behaviour.
Find guidance for speed, usage checks, missing QR codes, and support contact routes.
Getting Started
Use these answers before the first installation or activation attempt.
When should I activate the plan?
Activation timing depends on the product and destination. In most cases, install before travel and activate when you want the plan to begin.
Compatibility
These questions cover supported devices and common blockers.
How do I know whether my phone supports eSIM?
Check your exact device model against supported eSIM lists and confirm the device is carrier unlocked.
What if my phone is carrier locked?
A locked phone may block third-party eSIM installation. Confirm unlock status with your carrier before setup.
Usage and Data
Use this section for plan behaviour, speed expectations, and data checks.
How can I check remaining data usage?
Use the tools provided by MicroEsim for the relevant order, or check device-level data usage where applicable.
Can I make calls and send SMS with a data-only eSIM?
Many travel eSIMs are data-only. Voice and SMS may depend on apps, Wi-Fi calling, or your primary SIM setup.
Will speed match local 4G or 5G service?
Speed depends on local coverage, congestion, device support, and the product purchased. Network conditions vary by destination.
Troubleshooting
Use these answers when installation or day-to-day use does not go as expected.
What if I lost the QR code or cannot find it?
Check the original delivery email, order history, or support channel. If the code cannot be reused, contact support before attempting another installation.
What should I do if data is not working after arrival?
Verify the correct line is enabled, data roaming is turned on if required, APN matches the instructions, and the destination is covered by the plan.
