Take no notice of people who say they don't work. Activation was straight forward and quick at home in the morning before I left. I travelled across France, Germany, Austria and Belgium and the 4G never wavered. very satisfied. Review: Router sim card replacement - Unfortunately with most providers switching off their 3G I lost my Internet connection as 4G isn't stable enough at present in my location to maintain good Internet connection. Research shows o2 are only switching off 3G in 2025 and hopefully providers will have increased coverage range before cut off. O2 Sim card arrived as arrival date stipulated inside plastic mailing bag that held envelope with set up instructions and sim card. Followed instructions and had my Tp link Archer Mr600 connected to Internet on getting sim card activation email. Thumbs up to Richie who called me one evening, after ordering Sim, to see how the o2 sim worked out for me, once set up, and suggested a 3 network sim that maybe better for my area, but to call if there was any problems in getting set up sorted with provided sim card. So currently pretty stable on 3G. I have had 4G preferred and changed band from Auto to manual selecting Band 8 & 20 on router but noted signal strength drop from 3 to 2 bar and Internet drop out mainly in the evenings. So I've left it on 3G & Auto Band meantime. I'm not into online gaming and haven't had any issue watching Netflix through smart TV for the few days I've had Internet through purchased o2 sim. ## Features - UNLIMITED UK DATA + 30GB EU ROAMING Stay connected across the UK and Europe with fast, reliable 4G/5G data wherever you travel. - EASY ACTIVATION Activate the sim and go — no contracts, no ID, no commitments.

Avoid! *by A***E on 5 July 2026* Read all the instructions before and waited until I got to my destination to install and activate. SIM Card activated no problems and then...nothing.
