Envoi de SMS impossible depuis le Luxembourg
Résolu : le contact que je prenais n'avais pas le numéro de télphone correctement formatté.
En détail : l'erreur 21 = numéro de destination mal formé.
Most likely the destination phone number is formatted wrong, which can happen particularly when importing contacts via third-party tool.
In this particular case, I used My Contacts Backup for iOS to export my contacts to VCF, then imported from Gmail. In the process, some numbers were wrongly formatted as +61 0 4xx when they should be just +61 4xx, causing the highly uninformative error message above. (The 21 error code actually comes from the operator's network, and has nothing to do with Android as such.) Removing the extra 0 solved the problem.
Je viens de re-démarrer mon téléphone => pas de changement.
L'envoi ne fonctionne toujours pas. Erreur 21 encore.
Je viens de forcer un changement de réseau : passage de Orange-Lu à POST (opérateur Lux). Pas de changement : impossible d'envoyer, erreur 21.
