Regarding the three most recommended overseas SIM cards from a hundred comments in the comment section:

It seems that everyone has a need for overseas SIM cards. Thanks to many friends for their help with the recommendations about ESIM yesterday, providing a lot of useful information:

I asked @grok to summarize the core content and he identified the top three most recommended options (of course, this is based on my purpose: pure SMS reception, low cost, no need for calls/data).

Three effective pieces of information reflected on Twitter:

1️⃣ Cost and number retention:

Many people emphasize low-cost number retention (such as annual fees ranging from a few to several dozen yuan), with many options available to avoid high monthly fees.

2️⃣ Reliability and compatibility:

Some cards like Clubsim were mentioned multiple times, but there were reports of not receiving Telegram or Google verification codes;

US/UK/Hong Kong numbers are more popular due to good compatibility; VOIP numbers are easily intercepted by platforms, so it is recommended to use physical number ranges.

3️⃣ Other considerations:

Options that do not require data or calls are prioritized;

Some recommendations like XPIN @XPINNetwork or RedteaGO focus more on data but are not suitable for pure SMS needs; some users mentioned account suspension risks (like giffgaff recently facing issues).

Popular sources:

Many recommendations come from Hong Kong (like 3HK, Clubsim), the US (like Helium, Ultra Mobile), Europe (like giffgaff, simyo), and low-cost countries like Nigeria. Overall, the focus is on high cost-performance and easy accessibility, with purchases commonly made through WeChat mini-programs or apps.

Based on likes, mention frequency, and user feedback, I selected the top three recommendations (prioritizing your needs: pure SMS reception, low cost, no need for calls/data). These are the options with high consensus in the comment section, excluding those with obvious negative feedback (like Clubsim not receiving specific verification codes).

Top three recommendations and why they are good:

1️⃣ Helium Mobile (US number, free)

Why it's good: Completely free to obtain and use (download via the app, invitation code provided in comments like MWBGPQX), supports sending and receiving SMS without issues, US number compatibility is extremely high, suitable for registering overseas accounts like Telegram, WhatsApp, Google, etc.

No monthly fees or additional costs, easy number retention (automatically renews by connecting to the base station), the highest cost-performance ratio (zero cost). Many people in the comment section recommend it as a pure SMS solution, stable and does not require real-name registration.

2️⃣ giffgaff (UK number, about 80 RMB for 20 years)

Why it's good: Low initial investment (a card costs around 80 RMB, usable for 20 years, average annual fee only 4 RMB), no real-name registration, real number range, very stable SMS reception (users in comments have used it for two years without issues, calling it a "code receiving artifact").

UK numbers are friendly for overseas registration, no need for data/calls, and the cost for pure number retention is extremely low. However, there are a few reports of recent account suspension risks, so it's advisable to have a backup. Excellent cost-performance ratio, suitable for long-term use.

3️⃣ Ultra Mobile Paygo (US number, $3/month)

Why it's good: The US number's code receiving capability is "invincible" (emphasized multiple times in comments), reliably receives various verification codes, including Telegram and Google. Although the monthly fee of $3 (about 21 RMB) is not the lowest, it includes basic number retention, with no additional data/call costs. Strong compatibility, suitable for your registration needs; the comment section views it as a high-end stable option, with outstanding cost-performance in terms of reliability and ease of use (aside from the monthly fee, pure SMS performance is perfect).

Finally, thanks to @XPINNetwork for providing an ESIM data card, I will write a test report after testing it.
