1. Update to the latest version (v1.2.6). Previous version have problem sending MMS. If you can't upgrade coz your using ahem ones then thats your problem.

2. Make sure the settings are correct.

3. Did u activate MMS from your telco provider?

4. Did you fill out the Cellular Data Network in Settings --> General --> Network --> Cellular Data Network?

5. If the 'M' symbol did not turn green then it did not detect an active connection. Did u disable EDGE in bosspref?

6. Do u subscribe to EDGE/3G service? I know this is a lame Q but sometimes this is the culprit.

@Bernard Yeo
Since u can send MMS using other phone, that ruled out the problem with your maxis line. So now its the settings.

1. Can u surf using EDGE/3G in your iphone using the sim card (not using wifi)?

2. If u subscribe with 3G then the APN would be unet. APN net is for older sims (not 3G).

3. Can you post the setting in settings --> cellular data network and setting in Swirly for verifications?

If you can't surf the net with EDGE/GPRS then SwirlyMMS can't work too.

@Bernard Yeo
Good for you. Now that you can test SwirlyMMS, please pay for it if you intend to use it.

u can have paypal without credit card. Just look for those paypal sellers and they will top up your account.
