Solid deal, bit of a wait on the sim

Honestly this is one of the better sim only deals I've seen this year. The data is generous for the money and the coverage has held up on my commute. The only thing was the sim took a few extra days to arrive, longer than I'd hoped.

Signed up in ten minutes

Took me about ten minutes to sign up on the site, which was the bit I was dreading most, because I'd heard the port over could drag on for ages. It didn't, my number moved across within the day and I had no gap in signal. The only small niggle is the app asked me to confirm my address twice, which was a bit annoying but not a big deal. Happy so far.

Got the sim only plan for my contract

I signed up for the sim only plan when my old contract ran out and the sim turned up in the post a couple of days later. The plan is cheap and the data lasts me the month. Only little niggle is the app is a bit slow to load sometimes, but it does the job.

Got a new sim for my mum's phone

I set up a sim only plan for my mum's old phone after she wanted to keep her number. The sim arrived in a few days and the switch over was simple once I followed the steps in the app. Price is a bit higher than the cheapest deals I found, but the data is generous.

About Marshmallow

Marshmallow is a UK mobile and broadband provider that sells its services directly to customers online rather than through high street shops. The company offers SIM-only and handset contracts for mobile phones alongside home broadband, with plans aimed at keeping monthly costs predictable. Its service is managed through a mobile app and a web account, where customers can check their usage, manage their plan and contact support.

Marshmallow positions itself as a straightforward alternative to the larger networks, with a focus on transparent pricing and no hidden charges. Its customers are individuals and households looking for affordable connectivity without long-term complexity, though this description applies broadly to its target market rather than a fixed profile.
