Used it across five countries with no hiccups. After the first 15-minute setup, every profile switch is under 30 seconds.

WHAT BUYERS SAY
Trusted by travelers, devs, and dual-SIM seekers.
A representative slice of feedback from public reviews on AliExpress, Trustpilot, MyBestSim, and the RedFlagDeals / Howard Forums pSIM threads.
Works on my iPhone with the USB reader exactly as described. The STK menu lets me swap profiles without opening the app.
Reviewer · Trustpilot
The open-source LPA was the deciding factor over 5ber — if the company disappears tomorrow, my card still works.
Forum thread · RedFlagDeals
I have been using it for 1.5 years now. Used with several phones. Besides working well, the service and support are even better.

Trustpilot rating
3.8 / 5
Based on public review aggregation across Trustpilot, AliExpress and MyBestSim. 9eSIM consistently scores higher than 5ber and eSIM.me on reliability and customer support.
COMPARE
9eSIM V3 vs the alternatives.
Side-by-side specs against the three other physical eSIM adapters frequent travelers consider.
5ber's parent company iFree Group entered a financial crisis in late 2024; new sales stopped and customer service is offline. Cards already in customers' hands keep working only because they can be paired with third-party LPA tools — but anything tied to the 5ber app or cloud is effectively bricked. This is the lock-in risk of proprietary platforms. Both 9eSIM and ESTKme run open-source LPAs, so any community-maintained app continues to write profiles even if the vendor disappeared. Flagship single-card prices shown; specs cross-checked against vendor pages and Trustpilot review aggregations as of April 2026.
VENDOR LOCK-IN
What happens if the vendor disappears?
Most physical eSIM cards only work with their maker's app. If the company shuts down, you can't download new profiles directly on the phone — and the brand premium and any prepaid downloads you bought turn into dead weight. 5ber's collapse in late 2024 made this real, not theoretical.
When 5ber's parent (iFree Group) ran out of funding, the official app and cloud went down. Cards already shipped only stayed usable because they could be paired with community open-source LPA tools. Cards locked to a vendor-only app keep the profiles you already wrote, but you'd lose the ability to add new ones from your phone — and any pre-paid download licences become worthless.
"Open-source LPA" means tools like MiniLPA and EasyEuicc can manage the card directly. 9eSIM and ESTKme cards work with both their own app and community tools; the rest are locked to the vendor — when that vendor goes, the card itself isn't bricked but its main feature (downloading new profiles on a phone) is.
