Peace, mercy, and blessings of God be upon you. Communication is preferably by call. I have an internet booster that I bought new. And I only used it once. The booster is almost new and works with excellent performance. Please do not bargain. For calls (( Phone number appears when clicking the contact button ) ) I hope to communicate via call or WhatsApp at the number shown, due to my infrequent access to the site. Responding to private messages may be delayed.
