  1. Hi Kamlesh,
    Glad to hear from you.
    I think it is blocked. I tried putting external antenna on unlocked Airtel E5573s-606 MiFi router.
    This is the antenna I used.

    I could hardly get any gain. So, like you said it is probably blocked.
    Do you think I should follow this same process for connecting external antenna for Airtel E5573 also ?
    Also I want to buy Unlocked Huawei E3372H (Idea Logo) ? I sent you an email about that.
    Please reply to that email also.
