Haven, the UK holiday park operator, is set to provide 'increased connectivity' at its Hafan y Mor and Presthaven locations.
The company has entered into a multi-million-pound deal with Vodafone UK and Freshwave.
This move comes in response to the growing number of guests who value internet and phone connectivity during their holidays.
Hafan y Mor is one of Haven's largest holiday parks, with the Snowdonia mountains as its backdrop.
It offers an adventure village, two entertainment venues, and beach access.
The Presthaven site, located on the North Wales coast, provides guests with direct access to five miles of sand flats.
It features an entertainment venue, arcade, indoor pool with a flume, an outdoor pool, and activities for all ages.
The new service will benefit Vodafone customers visiting its parks, including holidaymakers, holiday homeowners, and park residents, as well as communities near the parks.
Primrose Valley Holiday Park was the first to undergo 4G and 5G enhancements earlier this year, followed by Kent Coast, Craig Tara in Scotland, and Marton Mere in Blackpool.
Haven CEO Simon Palethorpe, said: "We’re excited to announce that our exclusive partnership with Vodafone is now live, and we’re looking forward to providing our guests, owners and team with improved high speed 4G and 5G connectivity.
"Our new partnership also means the local coastal communities near our parks will also benefit from improved mobile data coverage."
Connectivity is valued at Haven holiday parks with 93 per cent of guests utilising the Haven app which can be used to book activities on-site or for dining reservations.
Andrea Donà, network director at Vodafone UK, said: "Our partnership with Haven and Freshwave means our customers are starting to enjoy some of the fastest mobile data speeds in the UK as well as a stronger and more reliable voice signal while enjoying their holiday.
"Vodafone customers will automatically benefit from superfast access via their mobile phones and devices around the park and inside holiday homes - whether that’s checking emails, streaming their favourite show or staying in touch with loved ones."
The partnership will introduce dedicated Vodafone 5G while improving existing 4G coverage at Haven holiday parks across England, Scotland, and Wales.
Simon Frumkin, CEO of Freshwave, said: "We’re delighted to be working on this innovative project which extends mobile connectivity to Vodafone customers in Haven parks and the communities around them.
"Haven understands the benefits mobile connectivity brings to both its guests and operations."
