If you're still paying your Optinet bill the long way — fishing for the paybill number, typing your account ID, double-checking the amount — there's a faster path. Here it is, step by step:
- Open the Optinet client portal on your phone (or tap the link in your monthly SMS).
- Sign in with your account number and PIN.
- Tap Top Up Wallet, enter the amount, and confirm. M-Pesa STK Push pops up on your phone.
- Enter your M-Pesa PIN. Done.
The credit lands in your wallet instantly and your service auto-renews on the next billing date. No paybill numbers to memorise, no typos in the account reference. Try it once — you'll never go back.
