For many Chinese living in the US, retaining their long-used local phone number is crucial. It not only maintains connections with family and friends but is also linked to various important accounts like banks, credit cards, social media, and school systems.

However, once you decide to return to China for development, this US phone number you've used for years becomes a tricky problem:

● Cancel it directly? Absolutely not. Banks, email services, and payment platforms often use SMS verification codes as two-factor authentication (2FA). If the US number is deactivated, you won't be able to receive these codes.

● Keep the original plan? The cost is too high. Paying tens or even hundreds of dollars per month just to occasionally receive a verification code, while enduring the inconveniences of international roaming, offers extremely poor value.

This dilemma of being "too expensive to keep, yet too essential to lose" now has a perfect solution. Through the number porting feature of the iTalkBB Prime China-US Dual Number App, you can permanently retain your US number at a very low cost and completely eliminate all communication worries after returning to China.

1. Why is Handling a US Phone Number So Complicated?

Before finding the best solution, many people try seemingly feasible methods but eventually encounter numerous problems.

a. Paying High Fees to Major Carriers Just to "Receive Texts"

International roaming plans from the big three US carriers (AT&T, Verizon, T-Mobile) typically cost $30-$50/month. Not only are they expensive, but you may also face issues like poor signal and delayed messages. Some banking services (like Zelle transfers) might even be restricted if they detect overseas roaming.

b. Choosing MVNOs That "Don't Work Well Abroad"

Mobile Virtual Network Operators (MVNOs) like Google Fi, Mint, Ultra might seem cheaper monthly, but they are essentially just "low-cost alternatives to local US plans":● Prepaid Limitations: Most require prepayment for 3-12 months upfront. If you port your number out early, the prepaid balance is usually non-refundable.● Localization Limitations: Their networks rely on T-Mobile/AT&T/Verizon. Normal usage cannot be guaranteed after returning to China.  ○ Mint / Ultra: Do not support international roaming. You will hardly receive any texts or calls after returning to China.  ○ Google Fi: Supports international roaming but is expensive. Texts and calls are not entirely free.

c. Operational Inconvenience

When in China, if you want to receive US SMS, you need to switch between two SIM cards or two phones, which is very troublesome.
