Kalle på 7 år og jeg havde en fest. En sjov og anderledes oplevelse. De 5 stjerner skal ses i lyset af virkelig god service og hjælp, særligt da vi ikke kunne finde de billeder vi havde lavet og kundeservice svarede meget hurtigt og derefter sendte billeder og video pr. mail. Super service.

Honest and customer focused partners I am very happy to work with Hologram, after having had another connectivity provider that was both less transparent as well as mostly dismissive of our existence untill we threatened to leave. Whenever we have anything to ask about we get good answers, and more help that our other alternatives were willing to provide. There are many alternatives that are good, but after reviewing our options we felt like this was the one really great option for us.

I've been using Hologram sims in my GPS tracker for several years and the network connectivity globally has been superb, the billing and web payments system is clear and guarantees there are no hidden or unexpected costs. Definitely sticking with hologram for future projects.

Easy to use administration pages, you can see every information about your IoT device you need. Price is affordable. There were absolutely no problems with the service, coverage, etc. in Hungary in the past 6 months.

"I switched to Hologram from another well-known provider after experiencing constant lag and disconnections. My customers were tired of hearing excuses about these issues. Since moving to Hologram, I haven’t received a single complaint—everything works perfectly. I especially love their customer support team, and I’ve even built custom features for my clients using Hologram’s API. It’s given me complete peace of mind for my business.
