Glossary of Terms, Acronyms and sales techniques designed to befuddle...

(Some of our competitors, may want to look away!)

Traditionally the telecommunication industry loves to baffle and bewilder their clients with terminology and sometimes smoke and mirrors. Here's our breakdown for you, hope it is useful and helps demonstrate our no nonsense honest approach to business and building partnerships with our existing and future clients. 

EOT or Buy-Out Fee

Early termination charge (EOT) and the Buy-Out fee mentioned above are legitimate charges levied by the incumbent provider in the event of the customer wishing to terminate (or leave) the contract early. This is usually calculated by the number of months remaining multiplied by the basic monthly tariff costs.

Minimum spend clause

Beware of a ‘Minimum Spend’ Clause. This is usually only used for large corporate customers when dealing directly with a Network. This clause requires the customer to spend a minimum sum of money over the contract term. This often enables provider to quote attractive and very low monthly tariff charges and bundle costs. However, here is the ‘Rub’, the clause requires you to spend far more than you have budgeted for over the contractual term. So, in the event of you wishing to leave at the end of the set contractual term, you find you will be charged for the outstanding Spend – Ouch! Often the trusted ‘Buyer’ you employed to reduce your costs and signed you in to this marvellous ‘cheap’ deal has left your business having collected his Bonus in cost reduction! Yep, we have seen it all …

The number of 5G ready devices is beginning to expand and they will eventually be the default.
