Code used too many times
Hi, I’ve been very sick for months, before I could insert the code you sent to me. After dowloading Microsoft Office 2021 Pro Plus Key Phone Retail Global, I wanted to enter this code, but it says it’s been used too many times, and I can’t use this software. Could you send me another one? Thank you. X.H.

Fantastic
I’ve bought about 10 office 21 keys (all with phone activation). Activation is via an automated phone call – no need to speak to anyone. Takes less than 5 minutes to activate, I haven’t had any issue with any of the 10 keys I’ve bought, will definitely be buying again, so cheap!

Simply Works (or not so simply). Worked first time for me following the instructions. Paid and got an email. Download 4.6gb file from microsoft, link in product description. Mount IMG file, easy in new versions of windows 10 or 11. Setup.exe. After install open an office app. Prompted for product key found in the email from royalcdkeys.com. Basic then gets advanced here 😉 Activation through phone *prompted to activate using internet* reading in the product description to activate over the phone, following instructions. Phone activation, activation wizard, select the correct country, call the toll-free number. 13 minute phone call, provided the 63 Installation ID numbers when prompted, entered 48 numbers as the Confirmation ID. Done, Worked, Updated. Me got all the numbers correct 🙂 Cheaper than “Hot Chips”

The key came reliably and worked. Activation by phone was super annoying and took a long time. It would be nice if the procedure was explained step by step in the email
