La distance \u00e0 l\u2019antenne relais, la bande de fr\u00e9quences, les obstacles, la charge du r\u00e9seau, l\u2019emplacement et l\u2019op\u00e9rateur utilis\u00e9 peuvent faire une grande diff\u00e9rence. Un r\u00e9seau 4G stable peut donc parfois donner un meilleur r\u00e9sultat qu\u2019un r\u00e9seau 5G faible.<\/p>\n<h3>Si cela ne fonctionne toujours pas<\/h3>\n<p>V\u00e9rifiez l\u2019\u00e9tat du service, puis testez une chose \u00e0 la fois.
