This is the Smarty community forum, we are Smarty customers, just like you, we do not work for Smarty.
The title of your post needs more detail so that we can try to help.
Mobile phones do not use antenna’s, so what equipment are you taking about ? I guess you are trying to use Smarty as a replacement for home broadband, which is against their terms and conditions.
If you've got an unlimited data allowance, a word of warning about using mobile broadband on a permanent basis - section 5.15 & 5.16 of SMARTY's terms & conditions state:
...
This SIM card should not be used as a permanent long-term alternative to home broadband. If we determine in our sole opinion that your use of the SMARTY Services is in breach of these Terms and/or exceeds that reasonably expected of someone using the Service for legitimate personal, noncommercial use, then we may at our discretion terminate (in accordance with Section 9), or Suspend (in accordance with Section 8), or restrict your SMARTY Service. As an example, without limitation, we consider that if you regularly tether more than 8 devices that this is unlikely to be legitimate personal, non-commercial use.
