This can depend on a number of factors. It can take just a few days or longer if there are delays in getting the correct documents to us, or if forms are incorrectly filled in.
If we have offered to buy you out of your current contract, we need you to provide us with the termination bill from your current network and an invoice from your business. This will then be processed and paid to you within 90 days as per our agreement.
As you have entered into a business to business contract, there is no 14 day cooling off period.
We provide a variety of flexible business mobile phone tariffs. Please contact us for more details.
A number porting form allows us to request with your current supplier to take over your current telephone numbers.
On the day of the transfer, you will lose signal on your old SIM card. Once this occurs, you can insert the new SIM into your device and the transfer will be complete. The only downtime that will occur is the time it takes you to swap the SIM cards over.
The networks ask for these to ensure there is no fraud taking place and it also helps with credit checks.
SIM cards are dispatched within 24 hours of your agreement being signed. Equipment will be ordered once we have processed your credit check with the network and received your PAC codes and numbers.
With all supplied equipment as per your agreement, you are enrolled in the Zusi protect scheme. Should your device be lost or stolen, this will help to cover the replacement costs of a graded device.
Asked Mark at Zusi to come up with a phone package to suit my business and he went above and beyond. Nothing was too much trouble and answered all my questions and very professional. The process of switching contracts was made simple by Mark and Hollie, and now I am saving money each month with an even better deal. I will definitely recommend to my family and friends 100%.
I recently moved over to Zusi as our mobile providers from Plan.com. The sales team were great, not too pushy. We moved network from O2 to EE, the transition was not smooth sailing as we had a few hiccups, but it was dealt with quickly and professionally by Hollie, therefore what more can you ask for. One month in, so far so good.
Great Company. Very easy to deal with. We run a business, so we needed a reliable company to provide phone & broadband services, which Zusi does not disappoint. Internet speed is great, and the phones are much cheaper as they work through the internet. Great customer service, Zusi keep doing what you’re doing!
Dealt with Zusi to change our gas & electricity provider at a rental property, saved us money, service was brilliant and they made the change over so easy for us. Will keep in mind for when other properties are due....
