+# EU4 3-failure switch phone run (2026-05-10)
+
+## Request
+
+BOSS asked to run the Europe set again with this policy:
+
+```text
+Each region switches to the next after 3 consecutive failures.
+Total attempts: 10.
+```
+
+Country order:
+
+```text
+italy -> poland -> spain -> england
+```
+
+Expected schedule:
+
+```text
+Italy x3 -> Poland x3 -> Spain x3 -> UK x1
+```
+
+## Runner
+
+```text
+/tmp/phone_verify_eu4_3fail_switch_total10.py
+```
+
+Log:
+
+```text
+/tmp/phone_verify_eu4_3fail_switch_total10.log
+```
+
+## Result
+
+Final phase:
+
+```json
+{"phase":"phone_failed_all","total_attempts":10,"order":["italy","poland","spain","england"],"rotation":"sequential_chunks_3_attempts","max_consecutive_failures_per_country":3}
+```
+
+No SMS was received. All activations were canceled.
+
+## Per-country summary
+
+| Attempts | Country | OpenAI selector gate | Activation IDs | Outcome |
+| --- | --- | --- | --- | --- |
+| 1-3 | Italy | `意大利 (+39)`, `IT` | `1006751549`, `1006752140`, `1006752704` | 5sim `RECEIVED`, `sms_count=0`; resend channel was WhatsApp; canceled. |
+| 4-6 | Poland | `波兰 (+48)`, `PL` | `1006753330`, `1006753872`, `1006754409` | 5sim `RECEIVED`, `sms_count=0`; resend channel was WhatsApp; canceled. |
+| 7-9 | Spain | `西班牙 (+34)`, `ES` | `1006755063`, `1006755710`, `1006756318` | 5sim `RECEIVED`, `sms_count=0`; resend channel was WhatsApp; canceled. |
+| 10 | UK | `英国 (+44)`, `GB` | `1006756925` | 5sim `RECEIVED`, `sms_count=0`; resend channel was WhatsApp; canceled. |
+
+## Important observations
+
+1. The new stale-tab cleanup worked. Before most OAuth recoveries, the runner emitted:
+
+```json
+{"phase":"close_stale_oauth_tabs","reason":"before_oauth_recover","closed_count":1}
+```
+
+This prevented the previous tab pile-up problem.
+
+2. Strict country/area-code gates worked for all tested regions:
+
+- Italy: `IT` / `意大利 (+39)`
+- Poland: `PL` / `波兰 (+48)`
+- Spain: `ES` / `西班牙 (+34)`
+- UK: `GB` / `英国 (+44)`
+
+3. OpenAI repeatedly showed WhatsApp delivery/resend:
+
+```text
+重新发送 WhatsApp 消息
+```
+
+Under BOSS's SMS-only policy, the runner did not click WhatsApp resend; it canceled the 5sim SMS activation and rotated.
+
+## Conclusion
+
+For this account/session/proxy path, these Europe regions also did not produce SMS via 5sim `openai` activation:
+
+```text
+Italy +39
+Poland +48
+Spain +34
+United Kingdom +44
+```
+
+The repeated WhatsApp resend signal suggests OpenAI is selecting WhatsApp delivery for these numbers/regions or risk state, so continuing to buy 5sim SMS-only numbers is unlikely to complete the phone verification unless the delivery channel changes or a different provider/number class is used.
