What's New in Cellesim

1.5.7

August 14, 2026

Added a clear warning before installation: do not delete your eSIM. If it seems not to work it is almost always a setting, but deleting is permanent and the QR code cannot be scanned again. Your data usage screen now shows that usage is reported by the network and can be up to 45 minutes behind. Cancelled lines are no longer attached to support requests.

Never buying physical SIMs again

The one-tap setup on iOS actually works perfectly. No weird APN settings to mess with. Cellesim is my go-to now.

Clutch feature

Love that they throw in a free VPN. Felt way safer checking my banking app on the hotel Wi-Fi in Bali. Connection was solid everywhere.

Worked instantly in Tokyo

Landed, tapped install, and had 5G immediately. The free VPN was a lifesaver for accessing my US accounts securely while traveling. 10/10.

So easy!

Didn't even need a second phone for a QR code. Just hit install and my iPhone was good to go for my trip to Canada. Super simple.

Free VPN is a game changer

Bought a plan for my Mexico trip. Hitting one button to activate the eSIM was too easy. The included free VPN kept my data safe at the hotel. Love it.
