I am on a 12 months Lebara prepaid SIM and recently had my phone stolen. How do I go about getting a SIM replacement? I email Lebara customer service to report and requested a new SIM but I haven't received any email from them yet. Should I wait a bit longer?
Their email support is useless. Go on their website and use the online chat feature.
Your quickest option might be to look for a $2 sim in a store (eg coles/woolworths) and see if they can activate that on your existing account.
