Review: No funciona la red de IZZI
Review: La configuration du routeur est facile à réaliser pour programmer les fonctions basiques, aucune compétence particulière n’est nécessaire. Pour la mise en œuvre des fonctions avancées il faut des compétences un peu plus approfondie, mais leur configuration n’est est pas compliquée à réaliser sur le routeur car les menus sont clair. Les performances du routeur sont bonnes aussi bien pour la réception du signal 4G que pour le débit, même avec les antennes d’origine. Le routeur assure couverture Wifi très correcte aussi bien en 2,4 GHz qu’en 5 GHz, le couplage WPS ne pose pas de problèmes. Petites critiques ; pour l’instant je n’ai pas trouvé d’explications sur le fonctionnement « double SIM » , mode normal /secours , agrégation de canaux ?. Ii manque une documentation complète à ce sujet et sur la possibilité de programmation en mode commande, car le routeur peut être programmé en mode AT.

## Questions & Answers

**Q: Is this router AT&T compatible?**
A: We use an AT&T SIM and it works great. Their corporate office will try to tell you it isn’t compatible because of their “switch to 5G” but that’s just because they’d rather sell you their inferior whole home hotspot. I did have to change some settings to get it working correctly, but the dudes at my local AT&T were super helpful with getting me up and running.

*by B***N on 26 July 2025*

I recently purchased this SIM card wifi Router, and I'm happy to share my thoughts on it. The product arrived in good condition and was well-packaged. It is designed for normal connectivity, but also Can use a Standard Cellular SIM card to Get internet. One of the standout features of this product is the Sim card specific feature. I found it particularly useful because regular land based internet is expensive and not portable. So I use a SIM card from a major carrier. The internet speeds I can using my cellular Sim card are plenty for my usage such as streaming videos and tv. On the downside, setting up the Router to propperly work with a sim card can be slightly challenging, This didn't prevent me from using the product, but it is worth noting for potential buyers. Overall, I would recommend to people looking for a reliable and affordable solution, It has met my expectations and I believe it would be a good fit for those who travel as well. If you're considering purchasing this product, I encourage you to read other reviews as well, as individual experiences can vary. I hope my feedback helps you make an informed decision.
