Sure Mobile customers may notice some problems in areas of Douglas and Onchan today (Sunday).
The company says it’s upgrading its site on Douglas Head, which also feeds a transmitter at Shoprite in Onchan.
The work will take place between 8am and 2.30pm and means a reduced signal in the vicinity of both masts.
The company apologises for any inconvenience but says after the work’s finished, there will be increased capacity in both Douglas and Onchan.
