@Akhail it is not clear what modem model are you using. Is it sim800 or sim900?

[vshymanskyy]

@Akhail please answer or I'm closing the issue.

[marabesi]

I am having the same problem running this example.

The SIM8000 connects fine, the network connects fine but for some reason the sketch doesn't connect to the broker.

[vshymanskyy]

I'm closing this as couldn't get more info about the issue.

[jeancaffou]

@vshymanskyy Same issue, more information in #265
