Is the ENC Mobile SIM legit? Who runs ENC Mobile and whether it is reliable (2026)
Yes, an ENC SIM is a real US carrier SIM. ENC Mobile is a US mobile carrier aimed at Chinese Americans and international students. Its website says it runs on the T-Mobile 5G network, claims more than 20 years of telecom experience and over a million registered users, and lists offices in Los Angeles and New York. The number is a real US +1 mobile number, not a VoIP number and not a shared number from an SMS-code website. If you are in China and want a US number that keeps receiving codes, the case for the US T-Mobile physical SIM (ENC) is simple: $28 (about ¥199) including the first month's 30 minutes and 100 texts, shipped to China and tested before dispatch, working after 3 steps and about 5 minutes.

"Legit" really means three questions: is the company a real carrier, is the card a real carrier SIM, and are there traps when you use it from China. This guide answers each one.
Company details follow the ENC Mobile website as of 21 October 2026, and the SIM's rules follow the LarkSIM product page. Rules can change, so check the pages on the day you act.
Who is ENC Mobile?
ENC Mobile (迎客移动 in Chinese) is a US mobile carrier built for people whose lives span the US and China, mainly Chinese Americans, international students and their families in China. Its website states:
| Item | What the website says |
|---|---|
| Network | The home page says service runs on the T-Mobile 5G network; plans come on two networks, ENC-T (speed) and ENC-A (coverage) |
| Size | More than 20 years of telecom experience and over 1,000,000 registered users, by its own account |
| Offices and stores | A Los Angeles office (San Gabriel, CA) and a New York office (Flushing); retail stores in California and New York |
| Support | English, Mandarin and Cantonese; China line 400-990-6699, US line +1 909-666-1188, or dial 611 from an ENC SIM |
| Payment and shipping | Cards, Alipay and WeChat Pay; free delivery in the US and mainland China |
A Chinese tech news report says ENC's parent company is Megatel Holdings, that ENC is an FCC-licensed mobile virtual network operator (MVNO), and that it has partnered with Chinese Students and Scholars Associations at US universities since 2022 (ifeng Tech, July 2026). That is a media report; ENC's own About page does not name a parent company.
A virtual operator does not build its own towers. It rents a major carrier's network and runs its own plans, pricing and support. Tello works the same way. So "ENC runs on T-Mobile" and "ENC is its own carrier" are both true.
Is an ENC SIM a real carrier SIM? How it differs from VoIP numbers, code websites and SIM stickers
When people ask whether ENC is legit, they usually worry about ending up with a VoIP number or a shared number. The common kinds of "US number" compare like this:
| Type | Who owns the number | Can it recover your accounts long term? |
|---|---|---|
| Carrier SIM (ENC, Tello, Purple SIM, etc.) | You, for as long as you renew | Yes, the number stays with the SIM in your hand |
| VoIP number (Google Voice, etc.) | You, but platforms can tell it is VoIP | Some platforms reject VoIP numbers for sign-up or verification |
| Shared number on an SMS-code website | The website, used by many people in turn | No, next time you log in the number may belong to someone else |
| SIM sticker | Not a number: a film that lets a locked iPhone take other SIMs | Unrelated to the number; ENC does not support sticker-unlocked phones |
ENC is in the first group. The US T-Mobile physical SIM (ENC) product page states: a US physical SIM on the T-Mobile network with a real +1 mobile number, not a VoIP number.
How to check that your SIM is genuine
- 1
Read the ICCID on the card
The card carries a long ICCID number. You enter it during activation, and the ENC site validates it first. - 2
Turn on Wi-Fi Calling
Connect the iPhone to Wi-Fi, insert the SIM, and switch on Settings → Phone → Wi-Fi Calling. When "Wi-Fi Calling" appears in the status bar after 3 to 5 minutes, the number is registered on the carrier's network. - 3
Ask ENC support to confirm the number
Dial 611 from the SIM, or call ENC's China line on 400-990-6699, to check the number's status. The carrier's own support gives the most reliable answers on activation, signal and number status.

The 3 real risks of using ENC from China
The company and the SIM are legitimate. What goes wrong from China comes down to how the SIM is used:
- check_circleForgetting to renew: this SIM's number is cancelled after 30 days suspended and cannot be recovered, and accounts linked to it stop receiving codes. Email support@larksim.com before the plan ends; the same plan costs ¥66–99 a month.
- check_circleA platform not sending codes: the SIM receives SMS codes normally, but each platform decides whether to send one, and some refuse certain numbers because of your IP or their own risk checks. No number can guarantee it. If a code does not arrive, check your network first and do not keep resending.
- check_circleNo Wi-Fi, no texts: in China this SIM does not use the cellular network; texts and calls go over Wi-Fi Calling, and the first activation needs an overseas network connection.
Verdict: legit, and suited to anyone in China who needs a long-term US number
ENC Mobile is a US carrier on the T-Mobile network, the number is a real +1 mobile number, and the SIM is a genuine carrier SIM. From China, renew on time and use Wi-Fi Calling on Wi-Fi, and you can keep the number for the long term.
