Cr\u00e9dit expir\u00e9.<\/strong> Les SIM malgaches expirent si elles restent inactives \u2014 la SIM elle-m\u00eame et les forfaits de donn\u00e9es individuels ont des p\u00e9riodes de validit\u00e9. V\u00e9rifiez votre solde avec *134# (Orange), *155# (Telma) ou *141# (Airtel). Solde z\u00e9ro = pas d&rsquo;appels ni de donn\u00e9es. Solution : achetez un voucher de recharge (disponible dans n&rsquo;importe quel kiosque de rue, \u00e9picerie ou boutique op\u00e9rateur). <strong>2. Forfait data \u00e9puis\u00e9.<\/strong> Votre SIM peut avoir du cr\u00e9dit mais aucun forfait de donn\u00e9es actif. V\u00e9rifiez le statut des donn\u00e9es avec *137# (Orange) ou *152# (Telma). <strong>3. Mauvais param\u00e8tres APN.<\/strong> Les trois op\u00e9rateurs de Madagascar utilisent tous le m\u00eame nom APN : <strong>internet<\/strong>, sans nom d&rsquo;utilisateur ni mot de passe requis. Allez dans Param\u00e8tres \u2192 Donn\u00e9es mobiles \u2192 APN et v\u00e9rifiez que c&rsquo;est correctement configur\u00e9. <strong>4. SIM mal ins\u00e9r\u00e9e.<\/strong> La poussi\u00e8re, l&rsquo;humidit\u00e9 ou un l\u00e9ger d\u00e9salignement peuvent briser la connexion. \u00c9teignez votre t\u00e9l\u00e9phone, retirez la SIM, nettoyez les contacts dor\u00e9s avec un chiffon sec et r\u00e9ins\u00e9rez fermement. <strong>5. Param\u00e8tres d&rsquo;itin\u00e9rance d\u00e9sactiv\u00e9s.<\/strong> Si vous utilisez une SIM locale malgache, assurez-vous que votre t\u00e9l\u00e9phone est configur\u00e9 pour utiliser la SIM locale pour les donn\u00e9es plut\u00f4t que de se rabattre par d\u00e9faut sur l&rsquo;eSIM ou un emplacement secondaire.
