Tried the CUniq eSIM after seeing it on TikTok… and wow, it actually works SO WELL!
I kept seeing TikTok creator @贝利说TV talking about CUniq’s eSIM with “dual numbers in one phone,” so I finally decided to try it — and honestly, it completely solved my biggest headache when using my China number overseas.
Here’s my real experience after landing back in China 👇
📱 My phone: US version iPhone (no SIM card slot) Before this, when I traveled home, I either had to pay crazy roaming fees or rely on friends’ hotspots… super inconvenient.
But after switching to CUniq eSIM, here’s what I found:
✔️ Super easy to apply
Just register on the website → pick a plan (I chose the HK$9 number-keeping plan) → scan the QR code in the email → done in 10 minutes.
✔️ Real dual numbers
You get a FREE +86 Mainland China number. Calls show as a local number + bank verification SMS works perfectly.
✔️ Costs dropped dramatically
I used to pay monthly fees for two physical SIMs. Now it’s HK$9 to keep the number and I only top up data when I need it — super flexible!
✔️ Airport landing test: PASS
The moment I landed in Pudong, the phone connected to the network instantly. No card swapping, no settings — just opened the app, grabbed a taxi, shared my location. Even my friend said, “Wow you didn’t disappear this time!” 😂
