Can I keep my current phone number?

What should I do if my SIM card is not working?
Work through these in order:
  • Ensure the SIM card is inserted correctly.
  • Check for network settings or coverage in your area.
  • Restart your device.
  • If the issue persists, contact our support team for assistance.
Can I use this SIM card internationally?
Yes, most of our plans include international roaming. Check your specific plan details for international coverage and rates.
Can I use a phone SIM in a tablet?
While it’s technically possible, most tablets aren’t built to use the call and text features included with standard phone SIMs. That’s why we offer a range of data-only SIMs, purpose-built to keep your business tablet connected wherever work takes you. These plans focus on what matters most — reliable data access without the extras you don’t need.
How do I replace a lost or damaged SIM card?
Contact our customer service and we will send a replacement SIM card. A replacement fee may apply.
