We are going back to our roots, and are now offering mobile plans! UBB came to existence by solving mobile signal problems in Canterbury, now we can offer our own mobile plans back by the One NZ network! Choosing your Ultimate Mobile Plan is simple, just pick the data amount you need each month. All plans (excluding the Starter Plan) have endless data, once you have reached your monthly data cap, speeds are just reduced so you can carry on doing what you need to do!
👍 Unlimited mins to NZ & AUS | 👍 Unlimited texts to NZ & AUS | 👍 5G Ready | 👍 WI-FI calling ready |
