Fantastic value, easy switch!

I switched to the Allnet Flat 40 GB and brought my old number. The whole process was smooth and the price is so much better than my previous provider! I had questions about the Rufnummermitnahme and their customer service was super quick to respond. I'm telling everyone about Mega SIM!

Good data, slow SIM delivery

I got the Unlimited Smart 5G plan. The data speeds were great once I received the SIM card. It took about 6 days to arrive, which felt a bit long. Customer service was helpful when I called.

hey, anyone know if mega sim lets you keep your old number? kinda wanna switch but don't want the hassle of changing my number everywhere.

M Mia V. 3 months ago

Yeah, totally. I ported mine over last month, it was pretty straightforward, just make sure you select it during the order process.

K Kevin 3 months ago

They do! You just tell them when you sign up. I think you need to make sure your old contract is already cancelled or ending soonish though for it to work smoothly. My friend did it with no issues.

thinking about grabbing one of those unlimited data plans from mega sim. is their 5G actually good? like, what network are they even on?

P Paula 4 months ago

It's the O2 network, aka Telefonica. My 5G speeds are usually pretty decent in cities, gets a bit spottier in rural areas though, as expected.

J Jared T. 4 months ago

Yeah, it's O2. I'm on one of their 5G plans and it's generally fine. Not as rock solid as Telekom maybe, but for the price, it's a solid choice for sure. Unlimited is actually unlimited too.
