We are just in the process of going through this at the moment; unfortunately I can't give you too much detail as we are under a very, very strict Non Discloser Agreement.
We looked at working with several networks including 3, Orange and Vodafone. Unless you have a proven route to market none of the networks will deal with you direct, the networks direct will be looking for a minimum of 60 - 75,000 customer sign up's per year, if you are unable to guarantee this number of sign up's they will make you go through an airtime aggregator. In order to deal direct we have had to commit to a minimum of 30,000 customers signups in year one and well over double that in year two and thereafter with some pretty stiff penalties if targets are missed.
We have teamed up with one of the networks mentioned directly. The basic cost of setting up as an MVNO is around £320K; sim cards cost around £1.20 each and there are a number of on-going costs totalling around 5k per month. Depending on your companies credit rating the network may ask you for a deposit, this could be as little as 100k to as much as 800k. On top of that you have marketing and customer acquisition costs, billing and direct debit collection costs. Remember you will not have subsidised handsets from the networks either so unless you will be operating a sim only MVNO you will have to buy these in and pay for them upfront!
So far we have spent around 6 months working on this and expect it to be another 4 months before we go live.
If you choose to go through an aggregator your set-up costs will be reduced to less than 100k and depending on who you partner with you could be up and running in less than 12 weeks. An aggregator will still expect you to have a route to market and will be looking for you to sign up a minimum number of customers each year but this will be much lower than dealing directly at network level. We looked at a number of aggregators and were close to signing up with a company called Transatel (
www.transatel.com) when one of the networks approached us directly and asked to work with us
Setting up an MVNO is not easy; I have had many a sleepless night with all the paperwork involved. Depending on the rates you manage to get you will need around 20,000 customers to break even.
Should you choose to go ahead I wish you all the luck in the World because you will need it!
