My BSNL Prepaid plan expired yesterday. Today, every recharge denomination is showing "Sorry, this number is not eligible for this pack" message. Tried using BSNL website/app and other 3rd party websites/apps. What's going on?
1
Recharge with traffic plan 106/107. Number is in grace 2 phase.
Recharge from Paytm,PhonePe,GooglePay,Amazon Pay or from any other Option but Not BSNL Selfcare App, 
They say this recharge is not valid for this mobile number and My Number is Active and has Ongoing Validity of Next Year and then I recharge my plan with Pockets ICICI App and My Recharge got successful 
use bsnl official app or portal
I sed to get the same error while doing from third-party apps.
But it worked for me when I did recharge from BSNL portal. Your case seems different here. Try to post on Twitter or call CC or Visit nearest BSNL office.
Dont tweet them, they will reply in 5to 6 days
Better go to nearest bsnl csc / exchange
Use bsnl portal
In grace period you can only recharge with 49 or above Plan vouchers. Top-Up/Data packs not allowed.
I get same issue, when I do it from the portal, I see message below. BSNL is such a mess.
Dear Customer, Plan and the Denomination / Voucher selected is not applicable to this plan
Bro recharge with rs@249 plan. You are eligible for that plan.
try check the recharge amount i had the same issue just recharged succesfully with 107 RS AMOUNT
