On why people is having data roaming issues on their phones, here's what I complied and what may happen:
Normally, there shouldn't be an issue. Also please be mindful when you are roaming, you are NOT USING SIMBA network. So if you go to a place with weak network and no data, please do not blame Simba. Blame the local Telco. We live in a highly urbanised country, we expect everything 100% covered. People overseas don't expect 100% coverage. Please la, if you are in area less populated or far flung, expect connection to be weak or slow. I have roamed in many European and Asian countries with Simba, no issues or whatsoever. I've also experienced weak connection while in Europe. Just move to a location with better connection lor.
So back to topic what might have happened based on experience and what people might have shared
1. Account not enough money. If you have used up the free allocated data and $0 in your wallet balance, you WILL NOT be able to continue use your data. Please top-up!
2. Phone settings. For those using Android, please turn on your data roaming and turn on mobile data. Many might have accidentally turn off mobile data.
3. Please also check your mobile data usage limit and remove any usage limits. This had happened to people here who shared before. After removing the data limit, it was resolved and the phone cut mobile data after hitting the limit. Some phones have separate overseas roaming data limit. Please just turn it off.
4. For iPhones, same thing, turn on data roaming and remove any usage limits. Please also turn off sync when overseas as iPhone always constantly sync and eats your data. When your wallet balance is $0, once after your free data is used up, you cannot use data anymore.
5. Locally, there were issues with people facing app slow loading times, resolution is to reset the APN. Please delete your APN and reset it up. APN should be TPG. Restart phone. If your phone is using physical SIM, please just remove it and re-insert.
5. Do a manual scan of network and connect to the network operators. Try anyone, if cannot connect means connect, chose until you can connect to one. Or refer to Simba website of their roaming partner.
Please feel free to add on more. And please, stop blaming Simba for all these issues. Most issues are due to user and phone issues. If anymore issues, just go to their service centre and replace SIM Card please
Thanks
