Changing phones is simple; making sure your number moves with you is the part people worry about. Whether you are upgrading to a new device, switching from a physical SIM to an eSIM, or replacing a card you no longer trust, How to Transfer a Mobile Number to a New SIM in the UAE is a routine procedure handled by e& (Etisalat) and du — and you keep your number, balance, and most of your plan settings through the whole thing.
This guide explains the two different situations people mean by “transferring a number,” walks through the steps for each, and covers the documents, timelines, and costs involved.
Quick Answer
To transfer your mobile number to a new SIM on the same network in the UAE, visit your operator’s store with your Emirates ID — or request a SIM replacement through the operator’s app — and your number is moved to the new SIM, usually activated within a few hours. Moving your number to a different operator (number portability) is a separate process: you apply with the new provider, which coordinates the transfer, and it typically completes within one to two working days.
How to Transfer a Mobile Number to a New SIM: Two Different Situations
People say “transfer my number to a new SIM” to mean two different things, and the steps differ:
- Same operator, new SIM (SIM swap / replacement): You stay with e& or du but need a new physical SIM or an eSIM — for a new phone, a different SIM size, or an upgrade to eSIM. This is handled entirely by your current operator.
- Different operator (number portability): You want to move your number from e& to du or from du to e&. This is a regulated porting process where the new operator arranges the move with your consent.
Below, both paths are covered step by step. If you only want to keep your number while switching providers, our companion guide on how to keep your mobile number when changing providers goes deeper into portability.
Transferring to a New SIM With the Same Operator
This is the quickest scenario. You are not leaving your provider; you just need your number on a fresh SIM card or an eSIM profile.
At a store
- Go to a store of your current operator (e& or du) with your original Emirates ID.
- Tell the agent you want to transfer your number to a new SIM. If you have the old SIM, bring it — it speeds up ownership verification.
- The agent verifies your identity against the registered account, issues the new SIM, and registers your number against it.
- Insert the new SIM (or activate the eSIM profile) and restart your phone. The number usually becomes active within minutes to a few hours.
Through the app or online
Both operators let you order a SIM swap remotely. e&’s published SIM replacement guide describes the flow: sign in to your account, open the order menu, choose mobile SIM replacement, select the account, then pick home delivery of a physical SIM or instant eSIM activation. You verify your details and place the order. Delivery typically takes one to three working days, while eSIM activation can be near-instant.
Documents needed
- Original Emirates ID (or the passport/visa the number is registered under).
- The old SIM if you still have it — helpful but not always mandatory.
If your line was originally registered under specific documents, check SIM card requirements and documents before your visit so you bring the right ID.
Transferring Your Number to a Different Operator
The UAE supports mobile number portability, so you can change providers and keep your number. The process is designed so the new operator does most of the work:
- Choose your new provider and plan. Pick the e& or du plan you want to move to.
- Apply with the new operator. Visit their store or apply online with your Emirates ID. You give written consent for the number to be transferred.
- Clear outstanding dues with your old operator — unpaid bills can block the port.
- Wait for confirmation. The new operator coordinates with the old one. You keep using your old SIM until the transfer completes, then you receive a message telling you to switch to the new SIM.
- Insert the new SIM. Once the port completes, your old SIM stops working and the new one takes over with the same number.
Porting typically completes within one to two working days. Keep your old SIM active until the new one starts working — do not cancel your old line yourself, or you risk losing the number.
What Stays and What Changes
| Item | Same-operator SIM swap | Porting to a new operator |
|---|---|---|
| Mobile number | Unchanged | Unchanged |
| Prepaid balance / data | Carried over in full | Usually lost — use it up first |
| Plan or package | Unchanged | You choose a new plan with the new operator |
| Bank OTPs and linked accounts | Keep working — same number | Keep working — same number |
| Old SIM | Deactivated | Deactivated by the old operator |
| Contract obligations | None new | Early-termination fees may apply with the old operator |
The biggest practical difference: prepaid balance rarely survives a port, so burn through your remaining credit and data before the transfer date. With a same-operator swap, everything carries over untouched.
Costs and Timelines
- Same-operator SIM swap: typically around AED 20–30 for a physical replacement SIM; eSIM activation is sometimes free. Activation itself takes minutes to a few hours at a store, or one to three working days for delivery.
- Number portability: the transfer itself is generally free, but you may owe the new SIM fee and possibly an early-termination charge if you are mid-contract with your old operator.
Confirm the current fees with the operator before proceeding, since charges are updated periodically. Never take a third-party site’s stated fees as final — check the official portal.
Before You Transfer: A Quick Checklist
- Back up your contacts — anything stored on the old SIM itself (rare these days, but possible) will be lost.
- Note your registered details. If the number is registered under an old passport or an expired Emirates ID, update your registration first — and make sure your ID itself is current by renewing it if needed. See how to update mobile number information, how to check mobile number registration details, and our UAE Emirates ID renewal guide.
- Use up prepaid balance before porting to another operator.
- Check contract status — postpaid users should confirm whether any commitment period is still running.
- Keep the old SIM safe until the new one is fully working, then destroy it by snapping or cutting through the chip.
Common Problems and Fixes
- New SIM shows “no service”: wait a couple of hours for activation, then restart the phone. If it persists, contact the operator — the swap may not have completed on their system.
- Porting delayed: the most common causes are mismatched ID details or unpaid bills with the old operator. Clear both and the port usually resumes.
- OTPs not arriving after the swap: wait 24 hours; banking and government app registrations re-sync once the network fully recognizes the new SIM. If a specific service still fails, re-verify that service’s mobile number binding.
- Old operator tries to charge you: check whether you were inside a contract commitment period. If you believe a charge is wrong, raise it through the operator’s complaint channel.
Frequently Asked Questions (FAQs)
Can I transfer my mobile number to a new SIM myself at home?
Partially. You can order the replacement through the operator’s app and insert the new SIM yourself once it arrives, but the transfer is completed on the operator’s system — either instantly for eSIM or when the delivered SIM is activated with your ID.
Will I lose my phone number during the transfer?
No — that is the entire point of the process. Your number moves to the new SIM. The only real risk is if you cancel the old line yourself before a port completes, which is why you should let the operators handle the timing.
How long does it take to transfer a number to a new SIM?
A same-operator SIM swap is usually active within a few hours (plus delivery time if ordered online). Porting to a different operator typically takes one to two working days.
Can I transfer someone else’s number to a new SIM for them?
No. UAE rules require the registered owner to verify with an original Emirates ID. The only exception is an authorized representative with proper documentation, and even then policies vary by operator.
Does my prepaid balance move with the number?
With a same-operator swap, yes — balance and data carry over automatically. When porting to a different operator, prepaid balance is generally not transferred, so use it up before the switch.
Is it better to get a physical SIM or an eSIM for the transfer?
If your phone supports eSIM, it is the easier option: no delivery wait, no physical card to damage, and activation can be nearly instant. Physical SIMs remain the safer choice if you swap phones often or use a device without eSIM support.
The Bottom Line
Transferring your mobile number to a new SIM in the UAE is low-drama when you go through the right channel: same operator means a quick SIM swap at a store or through the app, and changing operators means letting the new provider run the port while you keep the old SIM active until it completes. The three things that cause nearly every delay — expired ID, unpaid bills, and cancelling the old line too early — are all avoidable with five minutes of preparation. Bring your Emirates ID, use up prepaid credit before a port, and never throw away the old SIM until the new one is working.
