New 4G services have been switched on in Halesworth and Bungay.
It means that people in both towns will get faster access to the internet on their smartphones and tablets.
However a warning has been issued that there is a small chance that some 4G mobile signals, transmitted at 800 MHz, may cause interference to Freeview which is received via an aerial.
Because 4G signals are transmitted at a similar frequency to Freeview, TVs can pick up these signals which may cause interference. Signs of interference could include loss of sound, a blocky picture, or a “no signal” message.
A company called “at800” is however offering help to fix signal issues under government direction.
A spokesman said they will provide free support to households that rely on Freeview for TV and will resolve any interference.
Anyone who notices new Freeview interference should contact at800 on 0808 1313 800 or www.at800.tv/contact-us
