You can also message sellers and review them from their profile. ## How do I change my preferences? 1. Go to **Settings → Profile & Preferences**, or click your avatar in the top bar. ![The Account Preferences page with Login Settings, System Settings and Company Profile](https://help.telecomsxchange.com/assets/screenshots/buyer-preferences.jpg) 2. Change the fields you need (see the table below). 3. Click **Update Preferences**. You'll see "Your profile has been updated." If you changed your Public, NOC, Rates or Billing email, TelecomsXchange also sends a "TCXC Email change notification" to your main email. These are the sections on the page: | Section | What you can set | |---|---| | **Profile Image** | **Upload New Photo**: PNG only, 278x278 px recommended. Until you upload one, your avatar shows the first letter of your login | | **Login Settings** | **New Password** and **Confirm Password** (at least 8 characters; leave blank to keep the current one). **Login Username**, **Email Address**, **SMS Phone** and **RMD Number** are shown for reference; ask support@telecomsxchange.com to change them. | | **Security Settings** | **Enable Two-Step Verification** (a texted code at sign-in) and **Login Timeout (minutes)**: the idle time after which you're logged out. `0` means never. The new value applies to your current session as soon as you save. | | **System Settings** | **Send Daily Statistics Email**, **Max Allowed Price**, your **API Key** and **Allow API Access**. Clicking **Regenerate** replaces the key immediately, without **Update Preferences**; update any integration that uses the old one. See [Use the API](https://help.telecomsxchange.com/buyers/api/). | | **Company Profile** | Company and contact details, **Public Email**, **NOC Email**, **Rates Email**, **Billing / Accounting Email** and **Rates Subject Template** | To put several addresses in **Rates Email**, **NOC Email** or **Billing / Accounting Email**, separate them with commas and no spaces, for example `rates@example.com,noc@example.com`. Web users (team members) see a shorter page: they can change their own password and two-step verification only. The photo, Login Timeout and company settings belong to the main account. ## Which emails will TelecomsXchange send me? | Email | Sent to | When | |---|---|---| | Purchased Route Confirmation ("You're Interconnected!") | Main email | A few minutes after you buy a route. It includes the host, tech prefix, codecs and rate sheet. | | Rate updates | Main email and **Rates Email** | When a seller changes rates on a route you bought. Not sent for routes you've blocked.

The variables are `{{seller}}`, `{{route}}` and `{{product}}` (Voice or SMS). ## How do I message a seller? 1. Click a seller's name in **Market View** or **My Interconnections**. Their **Vendor Profile** opens, with company information, **Member Since**, an **Available Routes** table (each route with its capacity, a **Download Tariff** icon and a **Purchase Route** icon) and **Reviews** with the average rating, for example "4.5/5.0 (12 reviews)". 2. Click **Send Message**. 3. Enter a **Subject** and your message. 4. Click **Send Message**. The seller gets an email about your message, and you'll see it in your **Sent** messages. If the seller is anonymous, the message still reaches them and their name stays hidden; in your inbox they appear as "Anonymous Owner of Route *name*" (or "Anonymous Owner of DID Number *n*"). ## How do I read and answer messages? 1. Click the **envelope icon** in the top bar. A red badge shows how many messages are unread. 2. Choose **Inbox** or **Sent**. 3. Click **Read** next to a message. Messages from TelecomsXchange staff show the sender **TelecomsXchange**, and a reply shows an **In Reply To** link to the message it answers. 4. Type your answer under **Reply to this Message** and click **Send Reply**. You can reply only to messages addressed to you (not to your own sent messages). The seller gets an email about your reply; replies to TelecomsXchange staff stay in the portal. Replies to an anonymous seller are marked "(Anonymously)". ## How do I review a seller? 1. Open the seller's **Vendor Profile**. 2. Under **Leave Feedback**, choose a **Rating** from 5 - Excellent to 1 - Poor. 3. Write **Your Review** (more than 3 characters). 4. Click **Submit Review**. Your review appears under **Reviews** on the seller's profile, where other buyers can read it. ## How do I add team members? The main user goes to **Settings → Web Users** and clicks **Invite New User**; roles, blocking users and the **Logs → Web Access** log are covered in [Invite your team and review who logged in](https://help.telecomsxchange.com/buyers/web-users-and-access-logs/). ## What if something goes wrong? | You see | What to do | |---|---| | ERROR!

Each colleague gets their own login, so nobody shares the main password. See the Web Users guide for roles and the access log.
