goffgaff 现在发短信也没法保号了吗？

We notice you’ve been AWOL for a while. Use your SIM before 00:12 on 26 Mar 2026 to save your giffgaff number (xxxxxxxxxx) before it expires.

We don’t want you to go. So, use your giffgaff SIM to save your phone number (xxxxxxxxx) before it expires at 00:12 on 31 Mar 2026.

上面一条短信是 26 号收的，下面的是今天收到的。
我 2025 年 2 月 25 号发的短信保号的，现在 giffgaff 发短信都没用了？
