An eSIM is a SIM card that lives inside your phone as a small rewritable chip rather than a card you slot in. The "e" stands for embedded. The chip does the same job as a plastic SIM — it identifies you to a mobile network so you can use data, calls and texts — but because it is built in, you change carriers or plans by loading a new digital profile onto it instead of swapping hardware.
How does an eSIM work?
A physical SIM stores your subscriber identity on the card itself. An eSIM stores the same information in a profile that is downloaded onto the embedded chip. The lifecycle looks like this:
- You buy a plan from a carrier or a travel eSIM provider.
- They issue an activation profile, delivered as a QR code, an activation code, or a push straight to a carrier app.
- In your phone's mobile-network settings you choose "Add eSIM" and scan the code. The profile downloads over Wi-Fi or mobile data — this takes a minute or two.
- The phone now has that carrier's credentials. You pick which line handles calls, texts and mobile data.
- The eSIM connects to the network the same way a plastic SIM would. If it is a roaming-based travel eSIM, you turn on data roaming for that line and it registers as a visiting subscriber on a local partner network.
Most phones hold several eSIM profiles and let one or two be active at a time, so you can keep your home line and add a travel line without removing anything.
Is an eSIM available in Pakistan?
Yes, in two forms that are easy to confuse.
A local eSIM line from a Pakistani carrier
Jazz, Zong, Ufone and Onic issue eSIM versions of their normal SIMs. You get a Pakistani 03xx number, local calls and texts, and the carrier's data packages. Because it is a local line, the same rules as a physical SIM apply: biometric verification against your CNIC, and your phone must be PTA-registered. This is the option if you want a Pakistani number on an eSIM-capable phone.
A travel data eSIM
This is a prepaid, data-only profile you buy online — from Simless or an international provider — for use in another country, or on a phone that cannot take a local Pakistani SIM. It connects through an international roaming partner rather than registering with a Pakistani carrier, so there is no CNIC verification and no PTA requirement. It gives you mobile data only, not a phone number. Simless lists plans for 220+ destinations, including a Pakistan data eSIM for imported phones.
How much does an eSIM cost in Pakistan?
| Type | What you pay | What you get |
|---|---|---|
| Local carrier eSIM | A small one-time eSIM issuance fee, then the carrier's normal package prices | A Pakistani 03xx number, local calls/SMS, carrier data bundles |
| Travel data eSIM (abroad) | Priced by data allowance and validity — small bundles start low, unlimited plans cost more | Mobile data in the destination country, no local number |
| Pakistan data eSIM (for an imported phone) | Simless Pakistan plans start at about Rs 499 | Mobile data on a Non-PTA or imported phone in Pakistan, no 03xx number |
Carrier issuance fees and package prices change often, so take the current amount from the carrier directly. For travel and Pakistan data eSIMs, the live plan list shows the current PKR price, allowance and validity for each option, and the WhatsApp team confirms it before you pay.
Does your phone support an eSIM?
eSIM is a hardware feature, separate from the network or the PTA question. As a rough guide:
- iPhone: XR, XS and XS Max introduced eSIM, and the models released after them generally carry it, in most regions. US iPhone 14 and later ship eSIM-only.
- Samsung: Galaxy S20 onward, recent Note, and the Z Fold and Z Flip range typically support eSIM. A few region-specific variants omit the hardware.
- Google Pixel: Pixel 3 onward, subject to the model's sales region.
Region matters — two phones with the same model name can differ. Confirm your exact model on the device compatibility checker before buying any plan. Our compatibility guide walks through the three checks: eSIM support, carrier-lock status, and profile capacity.
eSIM vs a physical SIM
For everyday use in Pakistan on a registered phone, a physical SIM and a local eSIM do the same job; the eSIM just skips the plastic. The bigger difference shows up for travel and for imported phones: an eSIM lets you add a second line without a tray swap, install it before you fly, and keep your Pakistani SIM in place. The trade-offs — and the three situations where a physical SIM still wins — are in eSIM vs physical SIM. If you are weighing a travel eSIM against turning on roaming, see eSIM vs roaming.
Using an eSIM on a Non-PTA or imported phone
A phone brought in from abroad and not registered with PTA stops working on a local Pakistani SIM after its grace period. A local carrier eSIM will not help — it is still a local registration. A travel data eSIM does work, because it rides an international roaming partner and never registers the handset locally. You get mobile data, WhatsApp and app-based calling; you do not get a Pakistani number or SMS bank OTP codes. The full explanation is in eSIM for a Non-PTA phone in Pakistan, and the other routes for an imported phone are in Non-PTA phone options.
Get a data eSIM for your phone
Check your device on the compatibility page, then browse current plans in rupees. The WhatsApp team confirms the allowance, validity and PKR price for the exact plan before you pay anything.
Browse eSIM plansHow to get a travel data eSIM
- Check your phone model on the compatibility page and confirm it is carrier-unlocked.
- Pick a destination and plan from the plan list. For an imported phone used inside Pakistan, choose the Pakistan plan.
- Open the WhatsApp chat from the plan page. Support confirms the allowance, validity and PKR price, and you pay by a local method.
- You receive a QR code and instructions. Install while on Wi-Fi, using a second screen to display the QR code.
- Set the eSIM as your mobile-data line and turn on data roaming for it. On a prepaid travel eSIM, roaming is how the connection works and adds no charge.

Frequently Asked Questions
What is the difference between an eSIM and a normal SIM?
A normal SIM is a removable plastic card. An eSIM is a chip built into the phone that you load a carrier profile onto digitally. Both identify you to a mobile network; the eSIM just removes the card swap and lets you store several profiles.
Is eSIM available on all Pakistani networks?
Jazz, Zong, Ufone and Onic offer eSIM versions of their SIMs. Availability of specific packages and the issuance process can vary, so confirm with the carrier. Getting a local eSIM line still needs biometric CNIC verification and a PTA-registered phone.
How much does an eSIM cost in Pakistan?
A local carrier eSIM is a small one-time issuance fee plus that carrier's normal package rates — check the current figure with the carrier. A travel or Pakistan data eSIM is priced by bundle; Simless Pakistan plans start at about Rs 499, with the live price shown on the plan page.
Can I use an eSIM on a Non-PTA phone in Pakistan?
Not a local carrier eSIM — that is a local registration and needs PTA approval. A travel data eSIM does work, because it connects over international roaming. It gives you mobile data but not a Pakistani number.
Do I need Wi-Fi to install an eSIM?
You need some internet connection to download the profile. Wi-Fi is easiest. If you are activating a travel eSIM on arrival, install it before you leave home while you still have a working connection.
Does an eSIM give me a phone number?
A local carrier eSIM does — a Pakistani 03xx number. A travel data eSIM does not; it is data-only. Keep a registered local SIM for calls and SMS bank codes.
Can I have an eSIM and a physical SIM at the same time?
Yes, if your phone supports Dual SIM. Most eSIM-capable phones let you run one physical SIM plus one eSIM, so you can keep your Pakistani number and add a travel data line.
The short version
An eSIM is a built-in, software-loaded SIM. In Pakistan it means either a local carrier line (a real 03xx number, CNIC and PTA rules apply) or a prepaid travel data eSIM you buy online for trips abroad or for an imported phone. Check your phone on the compatibility page, decide whether you need a number or just data, and pick the matching option.
