Anyone encounter network issue after port in? My number after port in can't receive and make any calls, can't access to mobile data as well.
If you can receive SMS from DNC website (
https://www.dnc.gov.sg/) on your existing ported-in number (not the temporary number), and you can't access mobile data, and cannot make / receive calls, it means that the porting-in succeeded, but you are only on 3G. Why?
This is because your retailer screwed up the porting-in process. The retailer only did the porting in registration for you, but DID NOT TOP UP the $10 data plan for you. So, it means that your heya line is in a "limbo" state; technically, it is between the 60-day and 90-day expiry for those who are interested.
You need to go back to your retailer and ask him to top up $10 to your existing ported-in number, NOT the temporary number. This will provision / activate your line properly.
The proper process for the retailer in the first place is to do the porting in registration for you, take a picture of your temporary number, and immediately top up $10 to your temporary number. One visit should suffice.
Now you need a second visit. If the porting in succeeded, the temporary number is now dead, and the top up of $10 data plan should go to your existing ported-in number.
Once this is done (the retailer should not charge you extra because he already collected $10 from you during your first visit), you should get mobile data and be able to make/receive calls and have 4G voLTE reception within five minutes of the top-up.
Please let us know how you get on.
