My data isn't working

If you've just activated your SIM

If you've just activated your SIM and you've got a signal, you might need to check a couple of things to get your data working.

  1. Check that you have Data Roaming & Mobile Data turned on in your Settings.
  2. Make sure that you have changed your APN settings to match the following:
    Name: Ultra
    APN: wholesale
    User name: [leave this field blank]
    Password: [leave this field blank]
  3. Restart your phone
  4. If it's still not working, try the SIM in another phone to see if it'll work there.
If you've been using your SIM but suddenly your data has stopped working
  1. Check that you have data balance left by texting DATA to 6700
  2. Try turning your device off and on
  3. Try to remove the SIM from your device and re-insert it
  4. Check the coverage in the area you're in
  5. If your phone says it's connected to LTE or 4G but the data isn't working, try to manually turn off LTE/4G to connect to 4G/3G.


Settings > Mobile > Mobile data options > Disable LTE > Restart


Settings > Connections > Mobile Networks > Network Mode > Switch to 3G/2G > Restart

It might look different depending on your device! If these instructions don't match exactly, explore your settings until you find Network Mode

How do I find my mobile number?

You can only find out your number after you activate your SIM.

If you want to find it before you go, you'll need to activate your SIM online. The only catch is that your 30 days will start ticking once you activate!

How do I check my balance?

You can find your data balance by texting "DATA" to 6700.

How do I recharge?

As described on the website, the SIM is non-rechargeable. The only way around this is to buy multiple SIM cards and swap them out as you go.

What's the coverage like?

You can find the coverage map here.

How do I make calls/texts?

Local calls & texts

Simply dial the local USA number from your device. You may need to use a state code for landline numbers when calling interstate.

I keep receiving spam calls

Unfortunately, one of the drawbacks of SIMs in America is the number of spam calls you may receive. There are several spam-calling companies in the US that pester almost every number available! Ultra Mobile recycles old phone numbers so there might be a higher possibility that you may receive spam calls.

It's the last thing you want to be dealing with during your holiday and we wish we could stop this from happening but unfortunately, it's out of our control.

We apologise in advance for the trouble and we recommend you just block the numbers when they call or text.

How do I know if my device is unlocked?

If you bought your device outright, it's most likely unlocked!

If you're unsure, the best way to find out is to call your Aussie network provider and ask! They'll be able to unlock it for you too. This might incur a fee! 🤔
