Mobile customers who use EE have hailed the arrival of 4G in Stornoway.
EE's network will be supporting an emergency services network as part of a Home Office contract to modernise emergency services communications.
Na h-Eileanan an Iar SNP MP Angus MacNeil said that getting to this stage with mobile connectivity had been ongoing for a long time.
"I have and will continue to liaise regularly with mobile operators and vigorously campaign for improved mobile coverage in the islands," said Mr MacNeil.
"In November I met with representatives from EE who confirmed with me that they were looking to site in the region of 25 new masts across the constituency to provide 4G coverage along key roads that currently lack mobile coverage, together with upgrading existing sites to 4G.
“Improved mobile coverage is dependent on fibre broadband and at Westminster on Tuesday during a debate on the rollout of superfast broadband, I called on the UK Government to up its game on broadband.
“I appreciate that this is early days and that there may be teething problems, but this is a step in right direction and I look forward to seeing further progress throughout our islands.”
