Three has introduced new SIM-only plans with free 0800 calls. The plans include spending tools with the ability to set limits to stop customers going over their minutes allowance and spending limits on expensive numbers. For other 08 numbers - such as 084 and 087 - customers will be charged 5p per minute.
Customers can opt to change to a plan with increased allowances if they use more data than expected. The data allowance options are 500MB, 1GB, 2GB, 4GB and all-you-can eat data.
Personal hotspot is now supported in every new SIM plan; those on all-you-can-eat data plans can avail of a 4GB personal hotspot allowance. Three said it will introduce a 4GB data allowance to new contract handset plans in 2015.
Tom Malleschitz, marketing director at Three, said: 'People want choice and control so they are able to enjoy their devices without worrying about bill shock. These SIM-only plans give them exactly that.'
He continued: 'They’ll also benefit from free 0800 numbers and with Feel At Home customers can use the internet and call and text home while in Australia, France, Italy, the USA and twelve other countries out of their UK allowance.'
