1. Basic Mobile Number Portability (MNP) Process
The MNP process isn't complicated. Here are the basic steps:
- Choose a New Telecom Operator and Plan: First, compare mobile data plans from various telecom operators and choose the one that best suits you. You can check the latest offers through Broadband Price Finder.
- Apply for MNP with the New Telecom Operator: Apply at the new telecom operator's store, website, or through an authorized dealer. You'll need to provide your existing phone number and identification documents.
- Sign an Authorization Form: You'll need to sign an MNP authorization form, authorizing the new telecom operator to submit a porting request to your old telecom operator on your behalf.
- Wait for Processing: According to the Communications Authority's regulations, the processing time for MNP is generally 2 to 5 working days. During this time, your old number will continue to function normally.
- Activate the New SIM Card: After receiving the new SIM card from the new telecom operator, insert it into your phone on the specified porting date. The porting process usually takes a few minutes to a few hours.
- Confirm Successful Porting: After the porting is complete, the old SIM card will automatically become invalid, and your phone number will have been transferred to the new telecom operator. Try making and receiving calls to confirm.
2. 5 Essential MNP Tips
Tip 1: Confirm Contract Status and Early Termination Fees
This is the most, most, most important step. Before deciding to switch, you must confirm your contract status with your old telecom operator:
- Switching During the Contract Period: If you switch before your contract expires, you may have to pay an early termination fee (often called a "penalty"). The amount depends on the remaining contract period and can range from hundreds to thousands of dollars.
- Calculation Method: Most telecom operators calculate the penalty as "remaining months x monthly fee discount amount" or "remaining months x fixed amount." It's recommended to call your old telecom operator directly to inquire about the exact amount.
- Best Time to Switch: Start comparing prices and planning your switch 1 to 2 months before your contract expires, and execute the switch immediately after the contract expires to completely avoid penalties.
- Mobile Phone Installment Payments: If you purchased a mobile phone on an installment plan during the contract period, you may need to pay off the remaining phone installments in one lump sum when you switch.
Tip 2: Back Up Important Data
Remember to do the following backups before switching:
- Contacts: Ensure your phone book is synced to the cloud (iCloud or Google account) and not just stored on the SIM card.
- SMS Records: It's recommended to screenshot or use backup tools to save important SMS records.
- Two-Factor Authentication: If you use SMS to receive verification codes for banks or apps, there may be a temporary interruption during the switch. It's recommended to temporarily switch the two-factor authentication for important accounts to other methods (such as authentication apps).
- Value-Added Services: Check if you're using any value-added services with your old telecom operator (such as caller ringtones, cloud storage). These services will be automatically canceled after the switch.
Tip 3: Understand All the Terms and Conditions of the New Plan
Don't just be attracted by the monthly fee and data usage; also pay attention to the following details:
- Network Standard: Confirm that the new telecom operator's network standard is compatible with your phone. Although most phones in Hong Kong support the networks of all local telecom operators, some parallel imports or phones purchased overseas may have compatibility issues.
- Data Speed Limitation Policy: Some plans that advertise "unlimited data" will have their speed limited after exceeding a specified usage. Understand the speed and conditions after the speed limit clearly.
- Roaming Arrangements: If you travel frequently, pay attention to the new plan's roaming data arrangements and charges.
- Offer Period: The discounted monthly fee for some plans only applies to the first few months, after which it will revert to the original price. Confirm the actual monthly fee in the long term.
Tip 4: Choose a Suitable Time to Switch
The timing of the switch is also important:
- Avoid the Beginning of the Month: If possible, try to arrange the switch in the middle or at the end of the month, as most telecom operators charge monthly fees on a full-month basis. If you switch at the beginning of the month, you may be charged the full month's fee by the old telecom operator.
- Avoid Holidays: Telecom operators' processing speed may be slower during public holidays. It's recommended to switch on normal working days.
- Allow Buffer Time: Don't wait until the last day of your old contract to apply for the switch. Allow at least a week of buffer time in case of processing delays.
Tip 5: Keep Porting Records and Confirmations
- Keep All Documents: Keep copies of all documents, such as the new contract, MNP authorization form, and receipts.
- Request Confirmation Notice: Confirm the estimated completion date of the switch with the new telecom operator and request a confirmation notice to be sent after the switch is complete.
- Check the Final Bill: Carefully check the final bill you receive from the old telecom operator to ensure you haven't been overcharged. If there are any discrepancies, raise them promptly.
- Confirm Termination of Old Contract: After the switch is complete, confirm that your old telecom operator has officially terminated your service to avoid being charged continuously.
3. Common MNP Questions
Q: Will there be no signal during the switch?
A: There is usually a brief service interruption during MNP, generally lasting from a few minutes to a maximum of a few hours. In most cases, the interruption time is very short and will not have a significant impact on daily use.
Q: Can the old SIM card still be used after the switch?
A: After the switch is successful, the old SIM card will automatically become invalid and cannot be used again. It's recommended to dispose of or destroy the old SIM card properly.
Q: Can prepaid cards be ported?
A: Yes. Whether you are a postpaid or prepaid user, you have the right to MNP. However, prepaid users need to ensure that the number is still valid (not expired) before switching.
Q: How much does MNP cost?
A: MNP itself is usually free, but some telecom operators may charge a one-time administrative fee (approximately $50 to $100). Also, be aware of the contract penalties mentioned above.
Q: Can I switch from a postpaid plan to a prepaid card?
A: Yes. You can port to a prepaid plan from another telecom operator and keep your phone number.
